摘要:
An information processing apparatus in the present invention includes a receiving part that receives contents, an input part into which designation information to select desired contents is input from a user, a recording setting information generation part that generates recording setting information of contents to be recorded based on the designation information, an analysis part that analyzes relevance of content of the contents being recorded to be recorded based on the recording setting information to the designation information, and an acquisition part that acquires the desired contents of the user from the recorded contents based on an analysis result by the analysis part.

An apparatus of forming an evaluation signal used in adjusting focus bias and adjusting skew of a disk drive in which phase error information between a phase of a read data signal and a phase of a clock signal formed in synchronism with the read data signal, is detected, the phase error signal is converted into an analog signal and is outputted as an evaluation signal having a signal level in accordance with the phase error amount and the evaluation signal is inputted after A/D conversion to a portion for carrying out signal quality evaluation by using the evaluation signal whereby pertinent signal evaluation can be carried out by a simple constitution.

Method and apparatus for reproducing MPEG-compressed video data and compressed audio data from an optical disk having a diameter less than 140 mm and, a thickness of 1.2 mm±0.1 mm, with a plurality of record tracks having data recorded thereon as embossed pits representing information and exhibiting a track pitch in the range between 0.646 &mgr;m and 1.05 &mgr;m; with the tracks being divided into a lead-in area, a program area and a lead-out area. The data includes table of contents (TOC) information recorded in a plurality of sectors in at least one TOC track and user information recorded in a plurality of sectors in user tracks. The user information is comprised of MPEG-compressed video data, which may exhibit any one of difference MPEG formats, and compressed audio data, which likewise may exhibit an MPEG format, a PCM format or the like. The TOC information includes addresses of start sectors recorded in the user tracks and also includes application table of contents (ATOC) information which identifies various parameters for accessing and using the user information. The data (both user, TOC and ATOC information) is encoded in a long distance error correction code having at least eight parity symbols.

In the present invention, a partly duplexed conversion table is used as a conversion table for converting an M-bit based data string directly into an N-bit based code string without using margin bits. This conversion table is constituted by first and second sub-tables including plural code groups, respectively. The plural code groups include different codes for the same input data. The second sub-table is a table which is partly duplexed with the first sub-table and is produced by allocating different codes to data from first input data to second input data in the first sub-table. The first and second sub-tables are so designed that code sets of the duplexed portions take variants of digital sum variations which are opposite in sign. Codes are allocated to all the code groups in the duplexed portions of the first and second sub-tables with respect to input data sequentially from a code having a maximum absolute value of variant of the digital sum variation. Thus, according to the present invention, low frequency components of modulated signals may be restricted properly.

The data includes table of contents (TOC) information recorded in a plurality of sectors in at least one TOC track and user information recorded in a plurality of sectors in user tracks; with the TOC information including addresses of start sectors recorded in the user tracks. The data (both user and TOC information) is encoded in a long distance error correction code having at least eight parity symbols, and is run length limited (RLL) modulated.
摘要:
An optical recording medium has a multi-layer film including a reproducing layer and a recording holding layer, in which, while a readout light is radiated to the optical recording medium for transcribing signals magnetically recorded in the recording holding layer to the reproducing layer, the signals are converted by photomagnetic effects into optical signals which are read. Alternately, an optical recording medium has phase pits formed thereon in accordance with signals and changed in reflectance with temperature, in which, while a readout light beam is radiated to the optical recording medium and the reflectance is changed partially within a scanning spot the readout light beam, the phase pits are read. The track pitch p of pits RP of recording signals in a direction at right angles to the scanning direction of the laser light is set to not more than one-half the spot diameter of the laser light to raise the track density to improve the recording capacity of the recording medium.
