The optical information storage medium and a recording and / or reproducing apparatus is disclosed. Optical information storage medium is disclosed, in the optical information storage medium having a lead-in area, a user data area and a lead-out area, the data is recorded as pits in the lead-in area, a user data area and a lead-out area, wherein that does not change for the same physical format on the whole or a part of the lead-in area, information data is recorded and characterized in that the modulation method for recording data of the recording modulation method and the rest of the data in the other region. With the structure, simplify the manufacturing process and the signal of, so to form a pit with a depth shown at best possible to improve the recording / reproducing characteristic, and the data recording of a part of the lead-in area, a modulation scheme and a user data area by matching the data recording modulation method and the recording modulation method of a recordable optical information storage medium can maintain consistency with other types of storage media.
