摘要： A digital recording and reproducing method and system by which a desired control code can be recorded onto and reproduced from an analog record tape to improve the operability in reproduction of such analog record tape. A fixed head unit is used which has a first track face on which an analog head is provided and a second track face on which a plurality of digital heads are provided. Upon analog reproduction or recording onto or from one of a pair of analog tracks of a tape by means of the analog head, a desired control code is digitally recorded onto a non-recorded gap portion of the other analog track using a particular one of the digital heads. Then, upon analog reproduction by the analog head, the digitally recorded control code is read out from the tape using the digital heads.

摘要： A novel cassette changer for a tape player wherein a tape cassette accommodating member and a tape driving mechanism are fixed relative to each other during selection of a tape cassette and which has a comparatively small overall size and requires a comparatively low power for moving a tape cassette between the tape cassette accommodating member and tape driving mechanism. The cassette changer comprises a plurality of cassette receiving members each for removably receiving a tape cassette thereon, an accommodating member for receiving the cassette receiving members in a row thereon, an actuating means for selectively moving a cassette receiving members from a home position to a transfer position, a tape driving mechanism mounted in a fixed relationship with respect to the accommodating member for receiving a tape cassette thereon and driving a tape of the tape cassette, and a carrier for receiving a tape cassette from the selected cassette receiving member moved to the transfer position and setting the tape cassette in position onto the tape driving mechanism.
