ABSTRACT:
One of the preferred embodiments of the present invention provides an entirely novel thin-film magnetic-head assembly for a digital-signal recording/reproducing system using multiple tracks. The assembly comprises electronic-circuit components including a combined capacitor/resistor a constant-current source, an amplifier, and an analogue-signal multiplexer, all located inside a casing that surrounds the thin-film magnetic-head. These electronic circuits are present on the upper and lower surfaces of the casing and are connected by means of an elastomer so that these circuits are integrally connected to the thin-film magnetic head.
The thin-film magnetic head of the casing may alternatively be bent and extended so that electronic-circuit components can be mounted to it.
