Optical information storage medium and method of and apparatus for recording and/or reproducing information on and/or from the optical information storage medium
First Claim
1. An optical information storage medium encoded with data readable by one of a computer and a drive to implement a method of recording data in a lead-in area, a user data area, and a lead-out area, comprising:
- first data that is used for reproducing a first signal, and that is not modified depending on storage media to comply with the same physical format and is recorded in the entire lead-in area or a portion of the lead-in area using a first data recording modulation method; and
second data that is used for reproducing a first signal, and that is recorded in a remaining area of the optical information storage medium other than the entire lead-in area or the portion of the lead-in area using a second data recording modulation method different from the first data recording modulation method.

Abstract
An optical information storage medium and a method of recording and/or reproducing information on and/or from the optical information storage medium includes a lead-in area, a user data area, and a lead-out area in which data is recorded. The data that is not modified on storage media complying with the same physical format is recorded in the entire lead-in area or a portion of the lead-in area. A data recording modulation method used in the entire lead-in area or the portion of the lead-in area is different from a data recording modulation method used in a remaining area of the optical information storage medium.
