This digital master recorder uses the DAT (Digital Audio Tape system) standard making it compatible with all standard DAT recordings produced on professional as well as home recording equipment (consumer use). While fully realizing the tremendous performance potential of the DAT standard, the D-20B is designed to have the same operating "feel'’ and features of a conventional reel-tD-reel analog master recorder with two stereo tracks and a center track for SMPTE/EBU time code. As with all Fostex products, the D-20B is a rugged, reliable and sophisticated piece of equipment with superior sonic characteristics. The D-20B may also be used as a slave recorder for VCR, etc. when it is combined with a model4030 synchronizer. We, at Fostex, hope that the D-20B will help you in your creative projects. If you have any questions or comments about this or any other Fostex product, please do not hesitate to call your local Fostex Service Center. We will be glad to assist you in any way we can. Please read this manual carefully before using your D-20B to ensure proper understanding of all of its features. With proper care the D-20B, like all Fostex equipment, will give you many years of outstanding performance. Digital Audio Tape (DAT) technology is a recent phenomenon of the recording world. Using a variety of concepts from different recording formats, DAT is the perfect recording tool for those studios who demand the highest production standards. DAT employs a rapidly spinning rotary head module to encode and decode digitized information onto a standardized DAT tape cassette. In the D-20B, this format, formalized under the DAT, has been further improved by the inclusion of SMPTE/EBU time code recording. This means that the superior capabilities of digital recording can be synchronized to visual informatiari,i.e., film and television. Not only is the D-20B much less expensive to own and operate than a stationary head digital recorder, the DAT format is inherently superior in terms of tape costs and sonic integrity. DAT is a format that will revolutionize what engineers can do in the studio. While the technology is complex it is, in practice, a very simple formal to use. The D-20B has become a workhorse in recording, film, television and animation studios around the world. We at Fostex are proud to be the leaders in the field of professional DAT recorders and wish you the best in your creative efforts. Section 1. Outline of DAT Standard 5 Section 1. The D-20B is a master recorder for professional use that has been constructed using the standards that are under approval by the IEC. These standards, written in the IEC DAT standard book, cover the following six parts: DAT employs a rotary head type mechanism as showninFigure 1. By using high density tapes and this rotating head, two hours of information can be recorded on a small cassette. The rotary dram is 30 mm in diameter, revolves at 2,000 rpm and has a set of heads consisting of a plus azimuth type and a minus azimuth type placed, 180 degrees from each other. As the wrap around angle on the drum is 90 degrees, the reproduced h...
