摘要： An optical disk apparatus for suppressing a DSV and performing R-OPC. An encoding/decoding circuit inserts a synchronization information item to a head of only one synchronous frame when data are recorded on an optical disk. First, the encoding/decoding circuit inserts a synchronization information item having a polarity of either a mark or a space on the basis of a DSV. When the polarity of the first synchronization information item is a mark, the polarity of a next synchronization information item is set to a space. When the polarity of the first synchronization information is a space, the polarity of the next synchronization information is set to a mark. A system controller executes R-OPC at a timing when the synchronization information having the polarity of a mark is recorded on the optical disk.

摘要： A high-density optical disk and an optical disk drive therefor, which record data on lands and grooves are disclosed. Wobbles are formed in grooves and lands of an optical disk, and address information is embedded in the wobbles. The wobbles are formed so as to become in phase with each other in the grooves. An address of the land sandwiched between the grooves is detected from the wobble of the groove. When the wobble of the land is not an in-phase wobble but is of opposite phase, a gray code of the wobble is substituted with a binary address such that 0 is achieved when the gray code is converted into the binary address. As a result, even in the case of the wobble of opposite phase, the address information about the land is made coincident with address information about an inner-radius-side adjacent groove, thereby determining address information about the land.

摘要： In an optical disk of HD-DVD, data is recorded in both grooves and lands. A groove track includes its own data region called a groove (G) track address system formed therein and a land track includes its own data region called a land (L) track address system formed therein. One bit of address data is composed of four redundant wobble waves. When only three or two of the four wobble waves can be detected, an error is determined. When an error is determined in tracing of a groove track, bit data of the L track address system is used to correct the error. When an error is determined in tracing of a land track, bit data of the G track address system is used to correct the error.

摘要： An optical disk apparatus for suppressing a DSV and performing R-OPC. An encoding/decoding circuit inserts a synchronization information item to a head of a synchronous frame once when data are recorded on an optical disk. First, the encoding/decoding circuit inserts synchronization information as a mark or a space on the basis of a DSV. When the polarity of the first synchronization information item is a mark, the polarity of a next synchronization information item is also set on the basis of the DSV. When the polarity of the first synchronization information is a space, the polarity of the next synchronization information is set to a mark. R-OPC is performed at a timing when the polarity of the synchronization information is a mark.

摘要： A high-definition optical disk device for recording and reproducing data with respect to lands and grooves of an optical disk. The grooves and the lands of the optical disk are wobbled, and address information is embedded in gray code. In the grooves and the lands, both groove track address systems and land track address systems are embedded and form redundant systems. When detecting the address of a land, in addition to demodulation of the address data from the land track address system, the address data is also extracted from the groove track address system. The address data thus extracted is used for verification to detect an error in the demodulated address data.

摘要： In an optical disk of HD-DVD, data is recorded in both grooves and lands. A groove track includes its own data region called a groove (G) track address system formed therein and a land track includes its own data region called a land (L) track address system formed therein. When tracing a groove track, address information X is read from the G track address system, and also address information Y is read from the L track address system. If neither relationship X=Y or X=Y+1 is satisfied, it is determined that the address information X includes an error. Further, a groove track includes its own data region called a groove (G) track address system having a parity bit formed therein and a land track includes its own data region called a land (L) track address system having a parity bit formed therein. When tracing a groove track, address information X is read from the G track address system, and also address information Y is read from the L track address system. Even when the parity is correct, if neither relationship X=Y or X=Y+1 is satisfied, it is determined that the address information X includes an error.

摘要： An optical disk device which drives an HD-DVD or the like. When recording or reproducing data with respect to an optical disk of HD-DVD, the address information is demodulated by an address decoding circuit and is supplied to a system controller (S201). The system controller performs error checking using the CRC technique (S202). When a resulting CRC value does not correspond to CRC bits, the system controller regards a bit in which the number of waves in wobbles having the same phase is not four, which is a predetermined value, as an error bit (S103), and performs bit data replacement with respect to the error bit (S203). Specifically, the system controller searches for a combination of bit values by which a resulting CRC value matches the CRC bits, thereby performing error correction. At this time, the system controller tries the data value replacement preferentially using a combination of bit values by which the address is advanced by one address from the immediately previous address which is fixed among all the possible combinations with respect to the error bits.

摘要： An optical disk device which uses address information to perform a checking process on an optical disk. In an HD-DVD optical disk, data is recorded in both grooves and lands. A groove (G) track address system which is exclusively used for a groove is formed in a groove track and a land (L) track address system which is exclusively used for a land is formed in a land track. When the address of a target groove track is determinate and fixed to n, the optical disk device reads address information of the L track address system in the groove track and determines whether or not the address which is read corresponds to n or n-1. When the address which is read corresponds to n or n-1, the optical disk is determined to be normal. When the address which is read does not correspond to n or n-1, it is determined that the optical disk is defective.
