摘要： An information storage medium includes a drive zone having a plurality of physical clusters or ECC blocks. When new drive data is recorded in the drive zone, the new drive data is recorded in a physical cluster or ECC block next to the physical cluster or ECC block containing the most recently recorded drive data. In the method of recording drive data, the drive data is recorded in a physical cluster or ECC block of the drive zone. When the drive zone is updated with the new drive data, the new drive data is recorded in the physical cluster or ECC block adjacent to physical cluster or ECC block containing the most recently drive data. The drive data recording method is applicable to a new format of information storage medium.

摘要： An optical recording medium has a user data area and a lead-out area, wherein the user data area and the lead-out area each has grooves and lands formed thereon. Wobbles are formed on at least one lateral surface of grooves of the user data area and the lead-out area, and configured such that wobble characteristics are made different between the user data area and the lead-out area. Different types of wobbles are formed on the grooves of either the user data area or the lead-out area, thereby preventing an optical pickup that performs recording/reproduction from deviating from the user data area. Also, in a multi-layer optical recording medium, a whole area of a recording layer is configured to have a same condition, thereby preventing deterioration in reproduction and/or recording due to a difference in light power transmittance of another recording layer.
