    Abstract: An address unit is provided so that integer multiples of the address unit correspond to respective sector capacities of plural kinds of formats (such as the ISO format and the CD format) which are different in sector size. In this fashion, by multiplying the address unit by an integer, a sector of a respective one of plural kinds of formats can readily be accessed to.

    Abstract: A data recording method by which data of a compact disk can be recorded well onto a magneto-optic disk of the ISO format. Data of a compact disk are recorded onto a 5-inch magneto-optic disk (ISO format) of the 512 bytes/sector type of the CS system. The sector size of the magneto-optic disk is 610 bytes. Data included in one sector (98 frames) of the compact disk are 2, 352 bytes and subcodings of P to W are 96 bytes. Data for one sector are divided into data groups A to H to construct a data format. A CRC is added to each data group. Further, a parity 2 (Reed-Solomon code) is added. Data (3, 050 bytes) for one sector of the compact disk to which the CRCs, parities and so forth are added are recorded across 5 sectors of the magneto-optic disk. Data of a compact disk can be recorded onto a magneto-optic disk having a different sector size, and since error correction codes or error detection codes are added using the remaining area, the data can be recorded with a high degree of accuracy.

    Abstract: Data recording method suitable for use in CD-RAM (1) of a sample servo system. The length of a predetermined pattern made of data and one or more parities (corresponding to the length of one frame excluding a sync pattern and a subcode in an ordinary CD format) and the length between servo areas (corresponding to the length of one segment) have such a relationship that one of them is an integer multiple of the other. The data arrangement between the servo areas is arranged to form a predetermined pattern made of data and one or more parities. Relationship between the length of a predetermined pattern made of a subcode (12, 22, 42), data (13, 23, 33, 43, 53; 15, 25, 35, 45, 55) and one or more parities (14, 24, 34, 44, 54; 16, 26, 36, 46, 56) and the length between servo areas (11, 21, 31, 41, 51, 57) may be such that one of them is an integer multiple of the other and the data arrangement between servo areas may be arranged to form a predetermined pattern made of a subcode, data and one or more parities.

    Abstract: A method of recording a digital data signal, such as an audio PCM signal, onto a recording medium in the lon­gitudinal direction thereof, together with an apparatus which is suitable for this recording method. Even-­numbered words and odd-numbered words in a digital data signal are recorded on a first track group and a second track group, respectively, which are separated from each other in the widthwise direction of a recording medium, to prevent a series of words becoming error words because of, for example, a flaw in the recording medium in the longitudinal direction thereof. The data format is chang­ed at the input and output of a recording encoder to enable an error correction code and a recording circuit to be used in common for digital tape recorders which have different numbers of tracks, e.g., n tracks and 2n tracks. When an error correction code is recorded in such a manner that one word in the digital data signal is divided into a plurality of symbols which are formed into an error correction code, a plurality of symbols of the same word are recorded at a position at which error correlation is strong, making effective use of the error correction capacity of the error correction code.

    Abstract: A record that emulates a first recording format, which includes a track reference point, such as an index field, used for determining a position of a record on a track according to the first recording format, is recorded on a moving storage device operating according to a second recording format which also includes a track reference point by the following method. The method comprises the steps, responsive to location information generated according to the first recording format, of:

    (1) determining an original angular position of a record according to the first recording format;
    (2) calculating in response to the original angular position and a parameter a preferred angular position for the record according to the second recording format;
    (3) determining an actual angular position of the record recorded according to the second recording format; and
    (4) recording an extension of the record to compensate for the difference between the preferred angular position and the actual angular position.
