摘要： An optical disc (100) from which a plurality of pieces of information recorded along a track (9) by irradiating light that moves above the track relatively are reproduced in parallel. The optical disc has a disc substrate (1), and a recording layer (2) formed thereon. On the recording layer, a track is defined concentrically and two pit rows for carrying the plurality of pieces of information independently from each other are arranged along the track on the opposite sides thereof. At a specific position where the two pit rows are in a predetermined mutual relation and the plurality of pieces of information read out by irradiating light cannot be distinguished, at least one of two pit rows is shifted by a predetermined distance in the radial direction of the disc substrate by having the track as reference. Consequently, recording capacity can be increased relatively easily.

摘要： An information recording/reproducing device diffracts laser light into main- and sub-beams, irradiates evanescent light in relation to the main beam by an evanescent light generating element to a track where a recording pit provided on a recording surface of a recording medium is formed and evanescent light in relation to the sub-beam to be separated to a track where no recording pit provided on the recording surface of the recording medium is formed. A moving element moves the evanescent light generating element to change a gap with the recording surface. Return light in relation to the sub- and main-beam are received by sub- and main-light receiving elements, respectively. A control element controls the moving element so as to make the gap become a predetermined target value in accordance with a gap error signal containing a signal indicative of an amount of the return light in relation to the received sub-beam.

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.
