High Bit Rate Digital Recorder.

摘要

This report is the final report on a study program to demonstrate feasibility of recording and reproducing 240 Mb/sec digital data using magnetic tape. A transport employing two-inch wide tape and 64 track longitudinal recording heads was utilized as a feasibility model. The system included necessary electronics for operation on any 6 tracks on tape including all analog electronics, bit synchronizers, M(2) Encoders and Decoders, deskew electronics and the necessary multiplexers and demultiplexers. A bit packing density of 30 Kb/in/track was used and an over all raw bit error rate, without error detection and correction, and including all tape dropouts, of roughly 0.000003 was achieved. (Author)
