Abstract

In a recording and reproducing apparatus having at least one program recorded to recording tracks on a recording medium, management database is recorded on the recording tracks with the program so as to form a management database recording field. The management data is reproduced on being loaded the recording medium to the recording and reproducing apparatus to manage each program recorded on the recording tracks. In the case of video tape recorder, the management data is recorded on video recording tracks, audio recording tracks and/or a control signal recording tracks. therefore, to cover in the appended claims all such changes and modifications as fall within the true spirit and scope of the invention.

Claims

1. A video tape recorder for recording at least one program on a video tape, comprising:

recording/reproducing means for recording and reproducing signals on the video tape;

input means for receiving said at least one program;

display means for providing a display to a user;

user command input means for receiving recording commands from a user; and

control means for controlling the recording of said at least one program on said video tape by said recording/reproducing means;

said control means being operative to control said recording/reproducing means to record management data in a management database recording field formed at a predetermined position on said video tape, said management data including recording control data for subsequent display to a user carrying out a recording command input for indicating a recording condition of said video tape;

said control means being operative to control said recording/reproducing means to record data indicating an unused recording capacity of said video tape and to control said recording/reproducing means to record on said video tape data indicating a total number of programs recorded on said video tape and data identifying at least an identity and a total number of programs reserved to be recorded thereon as at least a portion of said data indicating an unused recording capacity of said video tape;

said control means being operative to control said recording/reproducing means to reproduce said recording control data from said management database recording field of said video tape and to control said display means to display a recording condition of said video tape based on the reproduced recording control data;

said user command input means being operative to input recording commands from a user responding to the display of said recording condition;

said control means being further operative to control the recording of said at least one program based on said recording commands.

2. The video tape recorder of claim 1, wherein said control means is operative to control said recording/reproducing means to record data indicating whether said at least one program has been recorded.

3. The video tape recorder of claim 1, wherein said control means is operative to control said recording/reproducing means to record data indicating whether said at least one program has been recorded completely.
