Abstract
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.
