Abstract
A recording/reproduction apparatus and a recording/reproduction method are adapted to information on the recording area of a recording medium without intervention of the operator if the recording medium is short of capacity necessary for recording the information to be recorded. If information not recorded on a magnetic tape is supplied to DTR 9 and central control section 2 determines that the magnetic tape does not have a recording capacity sufficient for recording the information, the central control section 2 causes the DTR 9 to record said information not recorded on the magnetic tape in the storage area of the magnetic tape storing one or more than one pieces of information with the oldest time and date of recording.

12. A recording/reproduction method comprising the steps of:
-
first recording information to be recorded in a first information recording means, including information of a time and date of recording on a first recording medium from a recording starting point of said first recording medium in an order of time and date of recording;
judging if said first recording medium has a remaining recording capacity sufficient for recording said information;
detecting one or more pieces of information having an oldest time and date of recording out of a plurality of pieces of information recorded on said first recording medium;
second recording of information not recorded on said first recording medium in a recording area of said first recording medium;
storing said one or more pieces of information having the oldest time and date of recording as detected in said detecting step if the information not recorded on said first recording medium is supplied and it is judged in said determining step that said recording medium does not have said remaining recording capacity; and
specifying one or more pieces of information recorded by said first information recording means on said first recording medium for prohibition of erasure;
wherein the oldest time and date of recording of said one or more pieces of information having been specified for the prohibition of erasure are changed to have a current time and date of recordings when said first recording medium is filled to capacity. - View Dependent Claims (13, 14)
