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.
