摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

摘要： Provided is a method for easily judging that a disc is an optical disc that conforms to the DVD Download standards, without generating malfunction. A Wobble signal is detected in a data zone (21) of an optical disc (YES in a step (S2)), CSS information is detected from a lead-in zone (20) of the optical disc (YES in step (S5)), and when attribute information, which is of the optical disc and recorded in the lead-in zone (20) of the optical disc, is further read and the disc is recognized as a DVD-ROM (YES in a step (S7)), the optical disc is judged as an optical disc that conforms to the DVD Download standards.

摘要： 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.

摘要： An optical disc drive and optical disc reading method according to the present invention is designed to perform a read operation with good stability even on a slim disc that could produce a significant axial runout. For that purpose, the optical disc drive determines, by the time it has taken for the number of revolutions of a motor that rotates the optical disc loaded to reach a predetermined number, whether the disc loaded is a lightweight disc or not (in Step 202 ). The drive also determines, by a signal obtained from the optical disc, what the size of the optical disc loaded is (in Step 204 ). And if the drive decides, based on results of these processing steps, that the disc loaded is a slim disc, then the drive increases the number of revolutions of the optical disc to a predetermined number or more in Step 207 to minimize the influence of axial runout.
