ABSTRACT:
A cassette having a recording medium contained therein for use with a recording/reproducing apparatus. The cassette includes a storage device for storing information pertaining to the recording medium and/or the cassette; a plurality of terminals coupled to the storage device and adapted to be coupled to the recording/reproducing apparatus when the cassette is being used therewith so as to transfer the stored information to the recording/reproducing apparatus; and an accidental-erasure prevention switch member located in close proximity to the terminals for inhibiting recording of an information signal onto the recording medium and inhibiting erasing of a previously recorded information signal from the recording medium. At least one hole and a window are provided in the cassette so as to provide access to the terminals and the accidental-erasure prevention switch member. Such at least one hole and window may be arranged so as to provide a relatively large area for fastening a label. The recording/reproducing apparatus includes a connector which is coupled to the terminals when the cassette is inserted and mounted in the recording/reproducing apparatus and adapted to receive the information from the storage device.
