摘要： A recording medium comprises pairs of groove tracks and land tracks provided side by side while being bent periodically, a plurality of land prepits previously formed on the land tracks and carrying information about the groove tracks, and a recording layer formed on at least the groove tracks and the land tracks. The land prepits have a radius of a curvature smaller than a radius of a curvature of sides of the groove tracks in land-prepit absent regions of the land prepits and are defined by curved surfaces continuously extending from the sides of the groove tracks. Those sides of the groove tracks which face the continuous curved surfaces of the land prepits are curved surfaces that stricture the groove tracks.

摘要： An error detector at a receiver comprises a feedback shift register. A shift direction in the feedback shift register is opposite to a shift direction at a transmitter in generating a transmission bit string by using a specified generator polynomial. A reception bit string is inputted to the feedback shift register in reverse order to the transmission bit string was generated at the transmitter so that errors in the reception bit string is detected by obtaining the remainder. Another error detector at a receiver comprises first and second feedback shift registers. Respective shift directions in the first and second feedback shift registers are the same as and opposite to a shift direction at a transmitter in generating a transmission bit string. The reception bit string is inputted to the first feedback shift register in the same order in which the transmission bit string was generated, while the reception bit string is inputted to the second feedback shift register in reverse order to one which the transmission bit string was generated. Errors in the reception bit string are detected by comparing respective remainders obtained by the first and second feedback shift registers. This reduces the processing time required for the error detection and increases efficiency in detecting errors in transmitted data.

摘要： An information recording medium is provided with a wobbled track, wherein at least a part of the track is subjected to wobbling based on a wobble signal in which at least a part of recording information is randomized. Each track is wobbled at a randomized frequency, so that a frequency of a wobbling signal obtained from the wobbled track is randomized. As a result, the influence of crosstalk between adjacent track is reduced.
