Cassette for storing data in a solid state memory in lieu of tape

摘要

A cassette type recording unit comprises a cassette casing, an IC memory, a magnetism-electricity transducer capable of magnetically coupling to a recording/reproducing head of the magnetic tape recording apparatus, a recording system and a reproducing system which are arranged between the electro-magnetic transducer and the IC memory, a magnetic detector to detect magnetism in an erasing head of the magnetic tape recording apparatus and a semiconductor switching circuit for switching from the recording system to the reproducing system and vice versa on the basis of a signal from the magnetism detecting element.
