Correlation between Anisotropy Direction and Pulse Shape for Metal Evaporated Tape

Measured replay pukes, recorded on Metal Evaporated tape, show a strong asymmetry and dependence on the direction of tape movement. It is found that pulse height and pulse width are unequal for both directions of tape movement. This is attributed to the non longitudinal easy-axis direction which causes differences in headtape geometry for both directions resulting in a different transition widt...

Ber Performance Comparisons in Digital Tape Recording

Bit-error-rate (BER) performances of various DC free coding and detection methods have been compared in digital tape recording environments. Performance sensitivities to additive noise, head-tape space variations and o track interference have been investigated at two representative linear densities. The results indicate that the performance ranking of di erent techniques depends strongly on the...

Storing Digital Data on Audio Tape

We have implemented a modem for digital storage onto standard audio tape. The primary goal of this project was to get a prototype system to function with very low probability of bit error. The prototype system is \soft" in that it is all done within Ptolemy except D/A and A/D conversion and, of course, recording is done on a cassette deck. The transmitter takes an input bit stream and modulates...
