Magnetic Media for the Digital Television Tape Recorder

Arthur R. Moore, Michael P. Sharrock

A general discussion of industry trends for magnetic media, with comments on new materials, is given. The digital television tape recorder (DTTR) requires the use of advanced particulate tapes to satisfy system needs. The tape requirements imposed by these needs are discussed. The tape industry appears to be capable of supplying media having the signal-to-noise ratios and error rates required, and will be addressing the reliability factors as the DTTR enters the marketplace. The DTTR 4:2:2 is designed to use 16 or 13-μm thick, 19mm-wide tape packaged in cassettes. The system is capable of making 20 generations of copies, while retaining broadcast quality. Details of the testing results obtained with the tape samples submitted to the SMPTE committee are summarized.
