## Abstract

A machine readable information storage medium, a reproducing method and apparatus which reproduces data from the storage medium, and a recording method and apparatus for recording data on the storage medium. The information storage medium includes a control area which stores within a data structure information usable by the recording or reproducing apparatus to record or reproduce the data on or from the storage medium. The information stored within the data structure includes a version corresponding to a specification, a revision number of recording speed, and an extended part version field.

## Claims

### Claim 1

A non-transitory machine readable information storage medium for storing data reproducible by a recording or reproducing apparatus,
the non-transitory machine readable information storage medium comprising:
a control area, said control area being configured to store, within a data structure, information usable by said recording or reproducing apparatus to record or reproduce the data on or from the non-transitory machine readable information storage medium, the data structure being configured to store
a version corresponding to a specification,
a revision number of recording speed, and
an extended part version field, wherein
the data structure is configured to store a maximum transfer rate,
the data structure is configured to store information relating to recording power corresponding to the recording speed,
the data structure is configured to store information specifying single layer or dual layer or another,
the control area includes data ID,
the data ID is configured to specify an area type corresponding to a lead-in area or another area,
the lead-in area includes the control area, and
the data ID includes a layer number.

### Claim 2 (depends on 1)

A reproducing method for reproducing data from the non-transitory machine readable information storage medium according to claim 1, the method comprising:
irradiating the non-transitory machine readable information storage medium with light; and
reproducing the data from the non-transitory machine readable information storage medium.

### Claim 3 (depends on 1)

A recording method for recording data on the non-transitory machine readable information storage medium according to claim 1, the method comprising:
irradiating the non-transitory machine readable information storage medium with light; and
recording the data on the non-transitory machine readable information storage medium based on the information stored on the control area.

### Claim 4 (depends on 1)

A reproducing apparatus for reproducing data from the non-transitory machine readable information storage medium according to claim 1, the apparatus comprising:
a module configured to irradiate the non-transitory machine readable information storage medium with light and to reproduce the data from the non-transitory machine readable information storage medium.

### Claim 5 (depends on 1)

A recording apparatus for recording data on the non-transitory machine readable information storage medium according to claim 1, the apparatus comprising:
a module configured to irradiate the non-transitory machine readable information storage medium with light and to record the data on the non-transitory machine readable information storage medium based on the information stored on the control area.
