Digital data recording and reproducing apparatus

Abstract

A digital recording and reproducing apparatus comprising a cassette number registering circuit ( ) for applying different CIDs for respective cassettes, a corresponding control circuit ( ) for searching, adding and deleting program data, a cassette number inserting circuit ( ) for inserting a CID in the form of a digital signal into the VBI of an analog video signal, a cassette number extracting circuit ( ) for extracting a CID from a VBI, magnetic recording and reproducing means ( ) for recording and reproducing the analog signal by using a magnetic tape ( ), a display number registering circuit ( ) for applying an AID which corresponds to a CID and is recognized by a user, a memory circuit ( ) for storing program data including a CID, an AID, a starting tape position, an ending tape position and recording start date, a program integrating circuit ( ) which makes one AID corresponds to a plurality of CIDs, and, keeps programs having later date and deletes programs having older date when the recorded magnetic tape positions of the recorded programs under the plurality of CIDs overlap. The above structure enable amendment when a plurality of CIDs are registered for one cassette by mistake. In integration, an AID of smaller number is selected. (FIG. )
