摘要： Provided are an optical disc recording device and a recording signal generating device which enable to correct displacement between a reproducing position of a reproduction signal from a concave-convex mark preformed in an optical disc, and a recording position of second information to be recorded in synchronism with the reproduction signal, and stably and speedily record the second information. A digital signal processor (202) specifies a reproducing position in the concave-convex mark, using a reproduction signal and a channel clock. A recording signal generator (211) generates a recording signal alternately including a plurality of additionally recordable data, each of which includes second information and has a predetermined length, and a plurality of dummy data. A recording position controller (110) detects a recording position displacement amount representing a displacement amount between the reproducing position and a recording position of the additionally recordable data, using the reproducing position and the reading signal. A recording length adjustor (208) increases or decreases the recording length of dummy data in accordance with the recording position displacement amount.

摘要： To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.

摘要： Data is read from a recording medium and the reproduced data is deinterleaved and stored to a first memory while input/output to/from the first memory is arbitrated. It is determined whether a predetermined number of data units is stored to the first memory. Based on the result data, it is determined whether transfer of the data stored in first memory to a second memory is permitted. If data transfer is permitted, the reproduced data is transferred from the first memory to the second memory, during which time input/output to/from the second memory is arbitrated. The reproduced data stored to the second memory is then error corrected, and user data contained in the error corrected reproduction data is externally output from the second memory.
