Recorder/reproducer and recording/reproducing method
First Claim
1. A recording/playback apparatus for recording or playing back data on recording media constituted by a first recording medium on which the data is recorded and a second recording medium on which information concerning the data is recorded, comprising:
- first acquisition means for acquiring, from said second recording medium, the information concerning at least one piece of the data recorded on said first recording medium;
first extraction means for extracting, from the information acquired by said first acquisition means, each recording-start position of said at least one piece of the data recorded on said first recording medium;
second extraction means for extracting, from the information acquired by said first extraction means, each recording-end position of the data whose recording-start position is extracted by said first extraction means;
accepting means for accepting selection of data to be played back from said at least one piece of the data; and
playback means for playing back the data from the recording-start position corresponding to the selection of data accepted by said accepting means, wherein the information includes the recording-start position and recording-end position of the data, and a recording date and time thereof, and is recorded on said second recording medium in a form which is collectively treated for each of said at least one piece of the data recorded on said first recording medium.

Abstract
The present invention relates a recording/playback apparatus that enables efficient management of data recorded on a tape. In an IC chip 32, information such as a recording-start position and recording-end position on the tape of the data recorded on a magnetic tape 31 is recorded in each unit of data. A main signal processing microcomputer 21 reads the information from the IC chip 32, and displays, on the display panel 18, a list of the data recorded on the magnetic tape 31. In accordance with determination of data to be played back from the list, the main signal processing microcomputer 21 supplies a mechanism control microcomputer 22 with a recording-start position on the magnetic tape 31 of the designated data. The mechanism control microcomputer 22 controls a mechanism motor 23 to play back the magnetic tape 31 from the recording-start position.

11. A recording/playback method for a recording/playback apparatus for recording or playing back data on recording media constituted by a first recording medium on which the data is recorded and a second recording medium on which information concerning the data is recorded, said recording/playback method including:
-
a first acquisition step for acquiring, from said second recording medium, the information concerning at least one piece of the data recorded on said first recording medium;
a first extraction step for extracting, from the information acquired in said first acquisition step, each recording-start position of said at least one piece of the data recorded on said first recording medium;
a second extraction step for extracting, from the information acquired in said first extraction step, each recording-end position of the data whose recording-start position is extracted in said first extraction step;
an accepting step for accepting selection of data to be played back from said at least one piece of the data; and
a playback step for playing back the data from the recording-start position corresponding to the selection of data accepted in said accepting step, wherein;
the information includes the recording-start position and recording-end position of the data, and a recording date and time thereof, and is recorded on said second recording medium in a form which is collectively treated for each of said at least one piece of the data recorded on said first recording medium.
