    摘要: An address data detecting apparatus comprises a gray code detector which detects gray codes of a land address and a groove address, a converter which converts the gray codes of the land address and groove address into binary codes, a position detector which detects a data uncertain position, and an address detector which detects the address data based on a detection result of the position detector and the gray code of the land address and the gray code of the groove address that are detected by the gray code detector.

    摘要: An evaluation method for calculating an identification signal by using PRML, comprises a table storing true patterns and ideal signals thereof, false patterns corresponding to the true patterns and ideal signals thereof, and Euclidean distance between the true pattern and the false pattern, a calculating unit, when a recording signal synchronized with an identification signal coincides with any pattern of the table, calculates a distance between Euclidean distance between the ideal signal of the true pattern and a reproduction signal and Euclidean distance between the ideal signal of the false pattern and a reproduction signal, and an evaluation unit which evaluates an identification signal by using an average and standard deviation of difference. A table for patterns is created for a likely mistaken pattern, whereby calculating an evaluation value with high precision, of a signal quality, with a small amount of calculation.

    摘要: An attempt is made to make it possible to efficiently perform the finalizing process and closing process in a short period of time and securely manage the last address of a border-out. When the border closing or finalizing process is performed after user data is recorded, a padding process is performed for at least a discontinuous area in the data area and a border-out is lastly recorded in a first step. Then, in a second step, latest recording management data (RMD) is recorded in a recording management data duplication zone (RDZ) of a data lead-in area, latest recording management data (RMD) is recorded in an unrecorded area of a present recording management zone (RMZ) and R physical format information (R-PFI) is recorded in an R physical format information zone (R-PFIZ).
