摘要： An optical information storage medium includes a lead-in area, a lead-out area, and a user data area between the lead-in and lead-out areas and in which user data is recorded. Pits are formed in the lead-in area, the user data area, and the lead-out area, and a track pitch in all or a portion of the lead-in area is different from a track pitch in the remaining area of the optical information storage medium.

摘要： An optical information storage medium includes a lead-in area, a lead-out area, and a user data area between the lead-in and lead-out areas and in which user data is recorded. A first track pitch between adjacent tracks in a first subarea of the lead-in area is greater than a second track pitch between adjacent tracks in a second subarea of the lead-in area other than first subarea and wherein the first subarea comprises optical storage medium-related information.
