Abstract: Data in the same signal format as a conventional CD is recorded to a first part of a record medium and compressed digital data in CD-ROM format in double density is recorded to a second part of the record medium. Addresses of a first session including the first part are represented in the notation of minute, second, and frame, and addresses of a second session including the second part are represented in binary notation. When the record position is moved from the first session to the second session, an end address of the first session is converted into an address of the second session. The start address is then designated and second addresses (for example, addresses represented in binary notation) are generated. When there is a non-record portion between the two sessions, an address value corresponding to the non-record portion is added to the start address. The resultant address is used as the new start address.

Abstract: An antenna is provided for use with a memory (MIC) incorporated in a recording medium that stores management data.

Thus, a recording/playback apparatus and a data library can be provided, which can use a large amount of information to manage the recording medium as management data before the recording medium is inserted into the drive.

Abstract: When a battery is in a standby mode, a microcomputer switches to a sleep mode when no charging/discharging current is supplied within a predetermined time and controls a timer to start measuring the standby time of the battery. When a charging/discharging current is supplied, the microcomputer switches to a wake-up mode and controls the timer to stop measuring the standby time. Then, the microcomputer reads the measured standby time. Based on the read standby time, the microcomputer calculates the correction value to correct the currently stored remaining battery capacity value.
