Abstract: A recording medium type detector detects whether the recording medium to be used is a bare disc or a cartridge type disc. When this detector detects that the recording medium to be used is a bare disc, then recording on the bare disc is disabled by a recording operation stopping section. Or, in such case, recording on another recordable disc is enabled.

Abstract: When the user enters a command to eject an optical disc from an optical-disc apparatus by operating an input unit, a CPU records information such as an operating mode and a location accessed immediately prior to ejection of the disc into a RAM unit as resume-function related information. The resume-function related information is then supplied to the optical disc to be recorded thereon by way of a write-in channel buffer, a switch, an ECC circuit, an RF & demodulation/modulation circuit and an optical head. Accordingly it is possible to make an access to a location on an optical disc accessed immediately prior to ejection of the disc from an optical-disc apparatus when the disc is reinserted into the optical-disc apparatus.

Abstract: A disk drive resumes supplying audio information without the hesitation normally attributed to disk access time. Initially, an indication is received that the disk drive should be deactivated. Next, audio information is stored from a beginning position, where audio information was last provided, to a resume position. Then, the resume position at which the disk drive should begin retrieving audio information, when the disk drive is reactivated, is stored. Finally, the disk drive is deactivated. In this manner, when the disk drive is reactivated, the stored audio information is supplied without the hesitation normally attributed to the disk access time of the disk drive.

Abstract: When a stopping instruction is given while a data file recorded in a recording medium is being played back, the position of the recording medium at which the stopping instruction was given is recorded so that a playback is started from the recorded position during a resume playback. Also, in a case where a data file is recorded in a recording medium, the recording position of a predetermined recorded data file is stored so that a playback is started from the predetermined position of the predetermined recorded data file during a playback.

Abstract: A drive device has a feed mechanism that causes a control object to move in order to control the positioning of the control object, a motor that serves as the drive source of said feed mechanism, and a control means that controls this motor The control means has an operation history memory unit that stores the operation history of whether the motor is doing an initial start or a restart, and a command selection unit that selects control commands and outputs them to said motor based on information stored in said operation history memory unit. Because intermittent operation that repeatedly drives and stops the motor occurs when there is a restart, the thermal shutdown associated with overheating of the driver IC is avoided, and any difference between the feed amount due to the control means and the actual feed amount can be prevented.

Abstract: A recording apparatus includes a feed roller which feeds a paper sheet, a feed motor which drives the feed roller, and a loss-of-synchronism detecting unit which detects loss of synchronism of the feed motor.
