ABSTRACT:
A magnetic recording and reproducing apparatus includes a deck to which a head drum is mounted to record and reproduce information with respect to a running tape, and a tape-end sensor to sense starting and finishing ends of the running tape. The tape-end sensor includes a light emitter mounted on the deck to project a light onto the tape being drawn and run from the tape cassette, a light receiver receiving light projected from the light emitter and transmitted through the tape, and a light interrupter blocking light projected to the light receiver that does not pass through the running tape.
