DIGITAL_DATA_WRITE_AMPLIFIER
Delivers 8-ma swing to record head. Rise time is 15 millisec, sufficient for nonreturn-to-zero re cording at 20 kc, using head with 50-mh inductance. Carrier-type amplifier overcomes usual stability and level problems associated with d-c amplifiers.-R. F. Shaw, Universal Tape Amplifiers for Digital Data Systems, Electronics, 31:41, p 91-93.
