Abstract

A recording device that can continuously record information data onto a plurality of information media without recording any particular information pertaining to continuous recording and without losing any information data is disclosed. The device records identical information overlapping onto two separate media for a predetermined time period.

Claims

1. A recording device for information media which records information data and management data on information media having an information data area for recording information data and a management data area for recording management data, comprising:

a recording and reproducing means for recording information data or management data onto information media and reproducing information data or management data from information media,

an overlap recording time period setting means for setting an overlap recording time period, and

a control and calculate means for calculating a single recording time period from a recordable time period obtained from the management data of said information media and the overlap recording time period which is set by said overlap recording time period setting means, outputting a signal for starting continuous recording when a time period lapsed after the start of recording of information data onto said information media is equal to the single recording time period, and controlling said recording and reproducing means to stop recording the information on said information media when the time period lapsed from the output of the signal for starting continuous recording is equal to said overlap recording time period.

2. A recording device for information media according to claim 1, said recording device is equipped with an output terminal to output said signal for starting continuous recording.

3. A recording device for information media according to claim 1, wherein said overlap recording time period setting means variably sets an overlap recording time period.

4. A recording device for information media according to claim 1, wherein said control and calculate means outputs a timing signal for stopping overlap recording when a time period lapsed after recording of said information data onto said information media is equal to said recordable time period.

5. A recording device for information media according to claim 1, wherein said control and calculate means controls said recording and reproducing means to record said management data which manages said information data recorded in said information area as one track, on said management data area of said information media.

6. A recording device for information media according to claim 1, wherein said control and calculate means controls said recording and reproducing means to record said management data, which manages said information data recorded in an information data area as a first track and said information data recorded in said information data area of two information media as a second track, on said management data area of said information media.

7. A recording device for information media according to claim 1, wherein said control and calculate means controls said recording and reproducing means to record said management data, which manages said information data recorded in an information data area and said information data recorded in said information data area of the current and former information media as a first track and said information data recorded in the said information data area of the current and the latter information media as a second track, on said management data area of said information media.

8. A recording device for information media according to claim 1, wherein said control and calculate means controls said recording and reproducing means to record said management data, which manages said information data recorded in said information data area of the current and former information media as a first track and said information data recorded in an information data area and said information data recorded in said information data area of the current and the latter information media as a second track, on said management data area of said information media.
