Mason, Terry, Fred Jr Thames, and John Howard. "‘NEW TECHNOLOGY’ DATA RECORDERS A TECHNOLOGY OVERVIEW." International Foundation for Telemetering, 2001. http://hdl.handle.net/10150/606457.
Full textThere are clear signs that data recorders using solid-state and disk-based technologies now represent a serious alternative to conventional linear and rotary tape recorders for a broad spectrum of data capture applications. As the number of RFQs specifying these so-called ‘new technology’ solutions increases, virtually every major manufacturer has responded with announcements of new off-the-shelf products. A NATO technical support team has even been tasked with drafting standards for certain aspects of solid-state and disk recorders. But what has caused this sudden explosion of interest? Strange to say, in almost every case it has been the perceived shortcomings of the new technologies which have forced the issue. For all their advantages, solid-state and disk recorders are essentially only temporary storage devices. To overcome this problem manufacturers have found it necessary to address the total data capture/storage/distribution/archiving scenario – with some interesting results. It is in the ‘data handling’ area therefore that some of the most significant advances are to be found. This Paper offers an overview of some of the new technology solutions now available - RAID (Redundant Arrays of Independent Disks), JBOD (Just a Bunch Of Disks) and FLASH memory recorders. New paradigms for airborne, mobile and laboratory data collection, handling, analysis and archiving are discussed, demonstrating that (for once) the migration path has been carefully thought through, with industry-standard data interfaces, true computer connectivity (Windows and UNIX) and familiar control techniques. It concludes that many users with a keen interest in replacing legacy products for whatever reason can now do so with confidence and minimal disruption to their day-to-day operation while nevertheless gaining access to the important benefits which ‘new technology’ solutions can offer.

Full textRecorders conforming to IRIG Standards have served the data recording community well for many years. Initially, most systems were analog in nature, recording data in either direct or FM modes but as the need for digital recording developed, the IRIG recorder was successfully adapted for this purpose by the addition of formatting and coding sub-systems to form the High Density Digital Recorder (HDDR). Today, user requirements for higher speed, higher capacity and more convenient systems have presented equipment designers with new challenges in terms of the correct choice of technology and system architecture. It is not surprising that system designers should turn for inspiration first to the very high speed transverse and helical products which had been developed for the broadcast industry since these technologies possess many of the attributes necessary for a high rate digital data recorder. It is unfortunate that it has now become a truism that the only logical progression from the longitudinal IRIG system is by means of rotary technology. Recent developments in a technology known as micro-track recording now call this assumption into question. Recording systems based on micro-track technology are available and others are in an advanced state of development, and these offer a costeffective, attractive and low risk alternative to rotary systems for both high rate data capture and tape mass storage applications.

Full textAs the performance of inexpensive commercial off-the-shelf (COTS) data storage devices continues to increase, the temptation to use them as the basis for data capture products for military and industrial applications becomes ever more compelling. For example, the Digital Linear Tape (DLT) format now offers a 270 Gigabits per cassette capacity at a sustained transfer rate of 40 Mbits/s – performance which would have cost tens or even hundreds of thousands of dollars per system just a few years ago. But to transplant such a device from its benign office habitat into a data capture product which will function reliably and consistently in a wide range of field and platform environments is an engineering task fully as difficult and complex as designing an environmentally robust recorder from scratch. This paper discusses the problems which typically have to be overcome; environmental protection, reliability, data integrity, power supplies, software issues, control and data interfacing, etc., citing practical examples of analog and digital DLT-based data recorders which are now entering service for telemetry, intelligence gathering, anti-submarine warfare and related applications

Full textDisk Recorders now represent a high performance, low cost and reliable alternative to traditional tape recorders for a wide range of platform data recording applications. This paper discusses the latest advances in disk-based recording technology in the context of multi-channel Telemetry applications, showing the degree of flexibility that is now possible in terms of both channel count and the ability to record synchronous and asynchronous digital data streams alongside multiple wideband analog channels. The techniques described are equally applicable to Acoustic, SIGINT and Telecommunications data capture and analysis applications aboard static, airborne and maritime platforms. Topics covered include how new disk-based data capture technologies have been able to extend bandwidth, storage capacity, signal fidelity and the overall capability of mission recorders. Advanced operational issues, including true ‘read-after-write’, data security, portability and archiving, enhanced data management and analysis strategies are also covered. The Paper includes detailed test results from COTS Disk Recorders already in service as well as an informative Road Map for this exciting new technology.
