摘要： A recording and/or reproducing apparatus for recording and/or reproducing data on or from an optical disc, in which the tracking error signal format for a recordable optical disc differs from that for a replay-only optical disc. The recording and/or reproducing apparatus includes a read-out processing unit for reading out data from the optical disc, a write processing unit for writing data on the optical disc and a system controller for managing control to verify the recordable optical disc having data recorded by the write processing unit by a reproducing system conforming to the standard for the replay-only optical disc. The recordable optical disc is verified by the reproducing system for the replay-only optical disc.

摘要： A recording medium of the recordable type in the form of a multi-layer disc or the like which is improved in compatibility and feasibility in use and a recording apparatus and a recording method ready for the recording medium are disclosed. A region for recording interlayer folding back position information is set on the recording medium (for example, “End sector number in Layer 0” or a session item type 3). In response to a fact that recording on a certain recording layer reaches a maximum recording range or that data recording advances from a certain recording layer to a next recording layer, interlayer folding back position information is recorded on the recording medium. This signifies that such recording is performed when advancement of the data recording to another recording layer is performed at a stage prior to disc closing or session closing or when it is predicted that such advancement of the data recording occurs soon. Also where the disc is of the type for which multi-session recording is performed, interlayer folding back position information is recorded with regard to a session in which folding back is performed.

摘要： The amount of light reflected from a disk is detected, and it is determined according to the amount of reflected light whether the disk is a recordable disk or a rewritable disk. The disk is controlled according to the result of determination such that it is rotated at a constant angular velocity (CAV) or at a constant linear velocity (CLV) and recording is executed. Further, rotation driving control of the disk is selected according to factors other than the type of the disk, such as according to whether random recording is allowed or not, according to a recording state in the disk, according to whether an alternative area is provided or not, according to a recording start position, or according to whether initialization is required or not. CLV control or CAV control is appropriately selected for a disk at recording to suppress a reduction in accessibility and a reduction in data transmission rate.

摘要： An optical disk driving apparatus includes a control computer, and the optical disk driving apparatus acquires a wobble signal. The control computer calculates an average period of a binarized wobble signal and a variance of the period of the binarized wobble signal. The control computer determines whether the calculated average period satisfies the specifications of DVD-R or DVD-RW and determines whether the calculated variance is below a predetermined level.

摘要： User data is recorded in a recording medium while being linked in units of a fixed length packet, and information indicative of this fact is written to the recording medium. At the time of reading the user data, the position of data linking block can be detected by making reference to the identification information, whereby the excessive run-out blocks which would be otherwise requisite to detect the position of the data linking block are made unnecessary. At the time of data linking, a part where data in the run-in block is missing is filled with correct data, thus the run-in block can correctly be read, whereby the excessive run-in blocks which would otherwise be requisite are made unnecessary.

摘要： The objective of the present invention is to facilitate to identify whether or not the optical disc is a optical disc of which recording capacity is enlarged. A synchronization pattern of ATIP information embedded into guide grooves irradiated with a light spot is made to be different between a high density optical disc and a standard density optical disc of which recording capacity is not enlarged. Specifically, while the synchronization pattern of the standard density optical disc is made into “3T+1T+1T+3T” (where “T” represents a minimum channel bit of a signal obtained by reading a positional information), the synchronization pattern of the high density optical disc is made into “3T+3T+1T+1T” for example. By reading the ATIP information and recognizing the synchronization pattern thereof, it can be easily and quickly identified whether the optical disc has a standard density or a high density.
