摘要： An optical disc, an apparatus and a method for recording/reproducing the optical disc use Gray coded address information. The hexadecimal data 0 to F correspond to the Gray codes. The Gray code consists of the upper address and the lower address. The four channels of the upper address and the four channels of the lower address are set so that one channel of each address is "1". With the change of the data from 0 to F, the channel of "1" in the lower address sequentially moves to the adjacent channel in the corresponding Gray code. Consequently, rapid seeking can be performed by detecting only the lower address.

摘要： A reproducing apparatus reproduces an information signal from a card type optical recording medium from which an information signal can be optically read out and on which an information signal is discretely recorded as a plurality of blocks each consisting of a plurality of track trains. The apparatus comprises a detector formed with a plurality of detecting elements arranged two-dimensionally. A light beam from a reproducing light source irradiates the entire area of the block as a recording unit. The detector detects light reflected from the optical card, and a extractor extracts a detection output of one of the track trains in the block on the basis of a detection output from the detector.

摘要： An apparatus for recording optical cards wherein checking words or inspection words based upon an error correction code are added to information data signals to be recorded, and signals which have been scrambled are recorded in the form of a block that can be optically read onto a belt-like optical recording medium of a card at intervals of a predetermined number of words that are distributed for a data track, and/or an apparatus for reproducing optical cards wherein signals that are read from the thus recorded optical card by a card reader, are descrambled thereby to reproduce the original data signals. Scrambling consists, for example, of so arranging the words that each is delayed by two words in the data track direction and that they are delayed by k tracks, where k is an integer, in the direction perpendicular to the data track, and placing the word at the head of the block at a position of a word number of which the phase is shifted by one word from the word number at the head of the block when the word that has reached the end of the data track is to be wrapped around to the other end and delayed, and then delaying each word by two words in the data track direction.

摘要： The present invention relates to an optical card reader, in which an optical card (1) having a plurality of parallel tracks T in which respective informations are recorded by the arrangement of optically recorded loci so as to be read optically is irradiated with a light source, the reflected light thereon is introduced into a photo detecting element (10) to thereby read the information, the photo detecting element (10) is controlled by scanning means (31) such that it scans each track T a plurality of times, of the plurality of scannings on the track T by the photo detecting element (10), an effective scanning capable of reading the information is detected by effective scanning detecting means 42 and on the basis of the detected output, an output signal of the photo detecting element (10) is extracted by extracting means (45) only during one scanning period of the scanning means 31. Thus, a contrast of a signal corresponding to the optically recorded locus is increased and a correct recorded information can be read stably without reading adjacent two tracks simultaneously.

摘要： An information recording processing constitution realizing both readout difficulty and high-precision readout is provided. Superimposition recording of highly secret additional information such as a cryptographic key in a groove signal recorded on a disk, which superimposition recording realizes both readout difficulty and high-precision readout, can be performed. The groove signal to which a phase error corresponding to a bit value is set is recorded at a time of recording of the additional information, and at a time of readout of the additional information, the phase error of the groove signal in a predetermined section is subjected to an integrating process and the direction of the phase error of the groove signal within each section is determined. The recording and reproduction of the additional information for increasing readout difficulty and realizing high-precision readout is realized by such processes.

摘要： Address information that has been error correction encoded is recorded on a second version of a recording medium after being transformed such that such that the address decoding cannot be performed by a playback device that is not compatible with the second version of the recording medium. The address decoding for the second version of the recording medium cannot be performed by the incompatible playback device (for example, a playback device that was manufactured to be compatible only with a first version of the recording medium). In other words, in the playback device that is not compatible with the second version of the recording medium, a state is created in which address errors cannot be corrected, so access is impossible (recording and playback are impossible).
