Abstract:
The materials used in magnetic recording heads have recently received a tremendous amount of attention. This has been the result of a fortunate set of circumstances. Ever-increasing demands for information storage, especially for graphics-intensive applications, have necessitated unprecedented increases in disk-drive areal densities. Combined with this are recent discoveries in the area of magnetoresistive materials, enabling the design and fabrication of much more sensitive recording heads. The end result is a flurry of activity that has come to dominate the field of magnetics. This article will explore choices for magnetoresistive read head materials, with an emphasis on the materials challenges.The recording heads that are used in high-performance disk drives typically consist of separate magnetoresistive read and inductive write heads (see Figure 1) where previously a single inductive head performed both functions. Separation of the two heads allows each to be optimized for their individual function, an essential factor in enabling disk drives to contain gigabytes of storage. The write head is the simpler of the two, consisting of a U-shaped ferromagnet surrounding a set of coils. The ends of the ferromagnet are the magnetic poles defining the write gap. When current passes through the coils, a field bridges the gap, setting the orientation of the magnetization in the media. Information is stored by changing the polarity of the current in order to write a pattern of magnetic domains in the media. The materials used in write poles will be reviewed in the section, Write Head Materials.

Abstract:
In this thesis both the static and dynamic magnetic behaviour of complex three-dimensional nanoscale commercial hard disk drive write heads and thin film structures of interest to emerging spintronic devices have been investigated using a plurality of experimental techniques. The magneto-optical Kerr effect (MOKE) provides the basis for an optical microscopy technique sensitive to the magnetisation of a sample, detectable as a change in polarisation of light reflected from the sample surface. With a modelocked laser light source, synchronised electrical pulse generator and lock-in amplifier (LIA), a stroboscopic technique has been used to observe the magnetisation dynamics of hard disk drive write heads at 600 nm spatial resolution and 10 ps time resolution in response to a driving electrical pulse. The equilibrium magnetic state of these devices has been directly imaged by x-ray photo-emission electron microscopy (XPEEM), as well the stability of the equilibrium state in response to the application of an external bias field. Direct images of the equilibrium state obtained by XPEEM were found to agree with inferences made from MOKE images. Time-resolved scanning Kerr microscopy (TRSKM) images of magnetisation dynamics showed that flux does not form in ‘beams’ as commonly believed, but instead nucleates in separate sites across the writer. Static and time-resolved x-ray techniques have also been used to investigate a number of thin films of interest to spintronics. Spin pumping and spin transfer torque in Co2MnGe / Ag / Ni81Fe19 spin valves were explored using time-resolved x-ray ferromagnetic resonance (XFMR) carried out at Diamond Light Source (DLS), a as well as static x-ray magnetic circular dichroism (XMCD) for sample characterisation. This has provided element-specific measurements of the spin state in the source and sink layers of the spin valve, revealing a clear sign of spin transfer torque, while also investigating the role of sink layer thickness in spin pumping and damping. Ferrimagnetic yttrium iron garnet (Y3Fe2(FeO4)3) (YIG), a material of great interest in spintronics, has been studied by static and dynamic XMCD in comparison with ferromagnetic Co. While static and dynamic spectra for Co were identical, those for YIG differed markedly. While this may hint at a phase difference between the precession of Fe moments on different lattice sites, the true source of this difference has not been identified. Comparisons between vector network analyser ferromagnetic resonance (VNA-FMR) and XFMR measurements further suggest the presence of long-range inhomogeneities in the YIG. The spin dynamics of an antiferromagnet being driven by a ferromagnet have also been investigated using XMCD and x-ray magnetic linear dichroism (XMLD). A CoO / Fe / Ni81Fe19 trilayer wherein the thickness of the CoO layer varies across the sample has been thoroughly characterised by static XMCD and XMLD, providing information necessary to fully interpret time-resolved MOKE measurements on these samples. Measurements have shown that even small amounts of ordered CoO significantly modify the resonant field and linewidth of the adjacent ferromagnetic layers. Phase-resolved measurements of CoO spins have shown these spins to precess in phase with those of the adjacent Fe. The viability of dynamic XMLD measurements has also been confirmed. Finally, potential directions for future work in each project are discussed.

Abstract:
碩士<br>國立雲林科技大學<br>企業管理系碩士班<br>93<br>The development of the hard disk has going through five decades. There are few industries like hard disk industry has sufficient and various technology developments. The key component technology- Read/Write Head has played an important role in this industry. It technology has been changed for four generation, from Ferrite Inductive Head, Thin Film Inductive Head, Magneto Resistive Head to Giant Magneto Resistive Head . Those technology revolution will sustain or intensity the product’s performance. All the technology revolution includes incremental and radical innovation. If we use the technology to development the S-Curve, we will find four phases of S-Curve. Each technology revolution will appear technology gap. This study attempt to use technology trajectory combines with patent indexes, to construct the head’s development trends. The patent indexes include “quantity” and “quality”. The part of quantity is adopted over the year’s the accumulation value of patent to construct head’s S-Curve. The other part of “quality” is adopted the technology cycle time (TCT) of patent citing relation to construct technology development trend. From the two technology development trajectories, we intend to present what situation will happen, while the technology brings revolution. Further, we evaluate the development trend of head. Through the research method we mention above, this study has already obtained the following conclusion: (1) In this industry, Samsung is a very competitive company, It actives in development the technology of head, so its future products will obtain sufficient technology supporting. (2) The technology development trajectory constructed by patent information can point out the phases of technology revolution; especially use the index of TCT. (3) The technology of Head will revolution oncoming, Using technology trajectory which construct by TCT index can appear the gliding trend in 2004. Therefore, we can judge the technology of head will be improved or go to the next generation.

Abstract:
碩士<br>國立臺灣大學<br>機械工程研究所<br>82<br>A model of a simulated computer hard disk drives was considered in this experiment. In the study, experiments have been performed for the ventilated flow of air between a pair of coaxial disks corotating in an axisymmetric enclosure with or without an obstruction in the form of a rigid flat rectangular bluff body (read/write magnetic head, arm). The effects of rotational velocity, throughflow velocity, and the position and the thickness of simulated read/write arm on heat (mass) transfer of disks were studied by haphthalene sublimation technique. The results show that the Sherwood number profiles along the radial direction of a disk are similar for all cases with or without arm between disks. The thicker and longer arm has indeed influence on heat transfer of disks under low rotational Reynold number and jet Reynold number , while the thinner and shorter one shows less effect. For high rotational Reynold number and jet Reynold number, the influence of arm on heat transfer of disk is not apparent.

Abstract:
Iron-cobalt alloys have been extensively studied as potential hard disk drive write head materials due to their potentially high saturation flux densities (~2.4T), low coercivities and ease of deposition. Iron-cobalt plating solutions have, however, been shown to have stability issues, necessitating that they be used at low pH or that a stabilizing agent be added to the solution. The purpose of this thesis is to evaluate the stability of a dibasic ammonium citrate plating solution and to characterize the deposits which result from its use. The plating solutions are found to be less stable than previously claimed. The solutions are oxidized by dissolved oxygen, which leads to a valence change in the iron ions and eventually the formation of iron oxide/hydroxide precipitates. These effects are exacerbated by heating or the application of a voltage across the solution. Deposits plated from the solution are fine grained (<40nm) and compact through their thickness. While normally deposited as the equilibrium BCC phase, metastable phases are deposited at elevated temperatures, high pH or in the absence of a stabilizing agent. A metastable phase which is isomorphous to α-Mn is deposited at elevated temperatures. This phase transforms to the BCC phase when annealed at >174ºC and is highly textured. Its presence is detrimental to deposit coercivity.<br>Materials Engineering

Full text
Abstract:
The thermal protrusion of a magnetic head was investigated through, first a high-resolution measurement of temperature distribution over the air bearing surface (ABS) and head coil and, second, a numerical calculation of the head protrusion. It was found that the temperature on the ABS results in a “butterfly”-shaped distribution. It was also found that an eddy current induced by high frequency write-current significantly increases the temperature of read/write elements. Moreover, the point of maximum temperature changed from the head core to the write gap when the applied current was switched from DC to AC. It was also found that a write-current induced head protrusion caused more deformation of the alumina over coat in the horizontal direction and that an ambient-temperature-induced head protrusion caused more deformation around the read-write elements. Furthermore, it is clarified that film materials with higher elastic modulus, lower expansion rate, and higher thermal conductivity reduce the head thermal protrusion. Finally, to reduce write-current-induced head protrusion, a novel thermally improved head structure is proposed.
