Abstract: An absolute time area is expanded by using an area of relatively low importance such as zero-data area and/or relative time area or the like in a Q channel in a sub-code in a recording format of a CD. Thus, an absolute time expression which can cope with a disc having a large capacity or the like can be performed. An absolute time expression is performed in a manner such that a digit of "100 minutes" is BCD expressed by using lower 4 bits in the 8-bit zero-data area ZERO. Thus, the absolute time of up to 999min59sec74frame can be expressed. A digit of "hour" is also expressed by using lower 4 bits in the zero-data area. For example, identification information showing that a disc is a high density optical disc of a large capacity is expressed by using upper 4 bits in the zero-data area ZERO.

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: AN OPTICAL DISK DRIVING APPARATUS INCLUDES A CONTROL COMPUTER. THE OPTICAL DISK DRIVING APPARATUS ACQUIRES A WOBBLE SIGNAL. THE CONTROL COMPUTER CALCULATES THE AVERAGE PERIOD OF A BINARIZED WOBBLE SIGNAL AND THE 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 SUFFICIENTLY SMALL.

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.

Abstract: A reproducing method for a record medium includes the steps of performing a demodulating process for data that have been read from a record medium on which content data have been recorded, management information and additional information being embedded in the content data, the management information being with respect to a copy management, the additional information containing one of error detection code and error correction code added to the management information, detecting the additional information from a demodulated output signal, performing an error detecting process corresponding to one of the error detection code and the error correction code, and controlling an output operation for the demodulated output signal for the content data read from the record medium corresponding to the management information when no error is found in the error detecting process.

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.
