    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 mean curvature smaller than a radius of mean 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 information recording device is used for recording record information in an information recording medium at least including a first recording layer capable of forming a first recording area and a second recording layer capable of forming a second recording area. The information recording device includes: write elements; acquisition elements for acquiring offset information indicating a relative shift; calculation elements for calculating an address (“Y′=Inv Y−α”) indicating a second boundary point opposing to a first boundary point according to the offset information; and control elements for controlling the write elements so as to write record information (i) while making the first boundary point a recording end or start position and (ii) making the second boundary point indicated by the calculated address a recording start or end position.
