Abstract
A recording and/or reproducing apparatus for use with an information storage medium that includes a lead-in area, a user data area, and a lead-out area is read by a recording and/or reproducing apparatus. Information about whether the information storage medium is compatible with a drive following an older version of standards is recorded in at least one of the lead-in and lead-out areas. Accordingly, the recording performance thereof is improved, and a drive following an older version of standards can record data on or reproduce data from a newer version of an information storage medium.
Claims32
A recording and/or reproducing apparatus for use with an information storage medium having a lead-in area, a user data area, and a lead-out area, the apparatus comprising:
- an optical pickup to transfer data with respect to the information storage medium;
- and
- a controller which controls the optical pickup to detect compatibility information about whether the information storage medium is compatible with a drive which uses a first version of standards older than a second version of the information storage medium and which is recorded in at least one of the lead-in and lead-out areas, and to control the optical pickup to transfer the data with respect to the information storage medium according to one of the first and second versions detected from the compatibility information which corresponds to a version of the recording and/or reproducing apparatus.
A recording and/or reproducing apparatus for use with an information storage medium having a lead-in area, a user data area, and a lead-out area, the apparatus comprising:
- an optical pickup to transfer data with respect to the information storage medium;
- and
- a controller which controls the optical pickup to detect strategy information recorded in at least one of the lead-in and lead-out areas information storage medium that differentiates between and indicates which one of a multi-pulse write strategy and a single-pulse write strategy is used to record the data, and to control the optical pickup to transfer the data with respect to the information storage medium according to the detected strategy information.
A recording and/or reproducing apparatus for use with an information storage medium having a lead-in area, a user data area, and a lead-out area, the apparatus comprising:
- an optical pickup to transfer data with respect to the information storage medium;
- and
- a controller which controls the optical pickup to detect strategy information recorded in at least one of the lead-in and lead-out areas information storage medium about an optimal writing pattern, and to control the optical pickup to transfer the data with respect to the information storage medium according to the detected strategy information.
