Abstract: The present invention facilitates identification of whether or not an 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 preferably 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 preferably 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.

Abstract: User data is recorded in succession to the recording of a guard block on a next recording layer when the user data is recorded with a recording position shifted from one recording layer to the next recording layer. If a record start position of the user data is learned beforehand in the next recording layer, the guard block is formed on the next recording layer prior to the recording of the user data. In other words, when recording layer shifting is performed, an area ahead of the recording position of the user data becomes the guard block so that a replay signal for use in a pre-replay process is obtained beforehand in the replaying of the user data.

Abstract: 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.
