Theory of Noise in Magnetic Recording Tape

Magnetic tape recording electrocardiograph.

R ECORDING the electrocardiogram for prolonged intervals presents difficulties from the standpoint of economy and convenience. One 200 foot roll of paper for a direct writing instrument is used in 40 minutes of continuous recording at 25 mm. per second, and reviewing this long electrocardiographic record is a cumbersome procedure. A convenient method of recording electrocardiograms and fied ele...

High Density Pcm Magnetic Tape Recording

The Bell & Howell Enhanced-NRZ recording reproducing technique for bit packing densities up to 40,000 per track inch is described in this paper. Utilization of the pulse code modulation format of Enhanced-NRZ achieves this high density with a bit error rate of one in ten million. Bell & Howell’s standard VR-3700B instrumentation tape recorder and wideband instrumentation recording tape are used...
