DIGITAL_CASSETTE_HEAD_DRIVE
Provides saturation recording as required for digital data. Back-to-back zeners provide bipolar limiting at ±10V, TTL-level inputs are applied to write data input, inverted by 7404, and fed to inverting input of opamp. Noninverting opamp input is INPUT referenced to +1.4 V so output will switch polarities when TTL level of input changes.-I. Rampil and J. Breimeir, The Digital Cassette Subsystem: Digital Recording Background and Head Interface Electronics, BYTE, Feb. 1977, p 24-31.
