摘要： A clock mark for extracting a clock when reproducing information from a recording medium and a synchronization mark for detecting a bit strip are recorded so that a part of the synchronization mark is identical to the pattern of the clock mark. A bit strip detection and a clock detection are simultaneously performed with one mark by multinary recording. Moreover, when recording information on a recording medium, a clock mark for extracting a clock when reproducing the information from the recording medium, a synchronization mark for detecting the bit strip, and a synchronization drawing mark for drawing phase synchronization at the position immediately after the synchronization mark are recorded. Even if a clock phase is shifted during reproduction, the phase shift can rapidly be recovered by using the synchronization drawing mark, thereby minimizing the error caused by signal lack.

摘要： The information such as address is to be efficiently formed into wobble components and further the S/N ratio in reproducing the information formed into the wobble components is to be improved. In an optical disc of the present invention, there are recorded in a wobble the address information modulated in accordance with the MSK (minimum shift keying) system and the address information modulated in accordance with a modulation system in which even harmonics signals are added to a sinusoidal carrier signal and in which the polarity of the harmonics signal is changed depending on the sign of the data for modulation.

摘要： A disk reproducing device comprising a variable gain amplifier (VCA) (32) that gives a radial push-pull signal including an address signal and an FCM leaking signal to a switch (38). The switch outputs only the address signal to a peak hold circuit (40) based on an FCM mask signal from a mask signal generating circuit (36). The peak hold circuit generates the peak hold signal of the address signal for outputting to DSP (30) that controls a VCA gain based on the peak hold signal. In addition, a radial push-pull signal having gain controlled based on the address signal is given to an address detection circuit (42), and the address signal is detected.

摘要： A track information table includes, for each track, decoding information, file pointer information indicating one of a plurality of files each with a header, and index information indicating a position within a file. A function is provided to attach a header to the index information track. The decoding information, file pointer information, and index information corresponding to a selected track are read from the track information table. The header of a file with a header is read based on the file pointer information. Information on a position within the file corresponding to the index information is extracted from the header. The data in the second half of the file is read based on the position information and is added to the track to which the data is to be added to create a new file with a header.

摘要： In step S1, an address generation block generates and pre-encodes a synchronization signal, address data, and address information composed of an error correction code of the address data which are to be recorded on an optical disc and outputs them to a modulation block. Simultaneously with this, a carrier signal generation block generates a carrier signal for carrying the address information and outputs it to the modulation block. In step 2, the modulation block MSK-modulates the carrier signal input from the carrier signal generation block with the pre-encoded address information input from the address generation block and the obtained MSK-modulated signal is output to a wobble formation block. In step S3, the wobble formation block forms on the optical disc a spiral groove wobbled in accordance with the MSK-modulated signal input from the modulation block. On this optical disc, an arbitrary address can be accessed rapidly.
