Abstract: 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.

Abstract: To provide write protection of a disc in a bare state that is usually used in a cartridge having a recognition switch for write protection, such as a DVD-RAM, write protection information is recorded in a Lead-in area, a Lead-out area or a recording information area other than a user data area of the disc, and the data is protected from unwanted overwriting or erasing using the write protection information. Even when the write protection information stored on a disc does not match the state of a recognition switch of a case for write protection, the data can be prevented from unwanted overwriting or erasing. Thus, write protection can be ensured when a recordable and/or rewritable recording medium, such as a DVD-RAM, a DVD-R or a DVD-RW, is used in a bare state.
