    摘要: An optical disk has a rewritable first recording area (5) and a read-only (2,3) second recording area. The first recording area (5) includes first tracks composed of groove tracks and land tracks formed on an optical disk substrate alternately in a spiral or concentric shape. Each of the first tracks is divided into a plurality of first sectors, and each of the first sectors includes a first header region having identification data (11a,11b) for identifying the first sector and a first data region (17) for recording user data by forming recording marks by changing optical characteristics of a recording surface. The second data recording area includes second tracks formed with physical concave and convex shaped pit rows arranged on the optical disk substrate in a spiral or concentric shape. Each of the second tracks is divided into a plurality of second sectors, and each of the second sectors includes a second header region having identification data (31) for identifying the second sector and a second data region having read-only data recorded as the pit rows. The first header region includes a physical concave and convex shaped first pit row. Each pit of the first pit row (21a,21b) has a width in a radial direction of the optical disk substantially equal to a width of the groove track and is wobbled outward or inward from a center line of the groove track by about a quarter of a pitch of the groove track. The second header region includes a physical concave and convex shaped second pit row (29). Each pit of the second pit row has a width in the radial direction of the optical disk smaller than the width of the groove track and is formed substantially along the center line of the second track.

    摘要: An information recording method has;

    a history determination step for determining whether or not a medium being cased and capable of being used for information recording and reproducing ,has previously been taken out from the case by using an identification section having historical information as to whether the medium has previously been taken out from the case or not ;and
    when a result of the determination shows that the medium has previously been taken out from the case ,

    for verifying correctness of information after recorded or recording after verification of correctness of information always or on condition that a predetermined condition is satisfied ,or inhibiting the recording , if the medium is a first recording/reproducing information medium that is required to use a case at recording ,and
    for recording normally if the medium is a second recording/reproducing information medium that is not required to use a case at recording.
