## Abstract

According to one embodiment, an information storage medium includes an organic dye material which records information with a light beam having a wavelength equal to or smaller than 620 nm.

## 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 useable 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 control area includes ID information,
the ID information indicating whether a data type is read-only data, and
the ID information containing a tracking method relating to at least one of a pit and a groove.

### Claim 2

A reproducing method for reproducing data from a non-transitory machine readable information storage medium including
a control area, said control area being configured to store, within a data structure, information useable by a recording or reproducing apparatus,
the data structure being configured to store
a version corresponding to a specification,
a revision number of recording speed,
an extended part version field, wherein
the control area includes ID information,
the ID information indicating whether a data type is read-only data, and
the ID information containing a tracking method relating to at least one of a pit and a groove, 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 relating to at least one of the version and the extended part version field.

### Claim 3

A recording method for recording data on a non-transitory machine readable information storage medium including
a control area, said control area being configured to store, within a data structure, information useable by a recording apparatus to record the data on 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,
an extended part version field, wherein
the control area includes ID information,
the ID information indicating whether a data type is read-only data, and
the ID information containing a tracking method relating to at least one of a pit and a groove, 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

A reproducing apparatus for reproducing data from a non-transitory machine readable information storage medium including
a control area, said control area being configured to store, within a data structure, information useable by said reproducing apparatus or a recording apparatus,
the data structure being configured to store
a version corresponding to a specification,
a revision number of recording speed,
an extended part version field, wherein
the control area includes ID information,
the ID information indicating whether a data type is read-only data, and
the ID information containing a tracking method relating to at least one of a pit and a groove, 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 relating to at least one of the version corresponding to the specification and the extended part version field.

### Claim 5

A recording apparatus for recording data on a non-transitory machine readable information storage medium including
a control area, said control area being configured to store, within a data structure, information useable by said recording apparatus to record the data on 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,
an extended part version field, wherein
the control area includes ID information,
the ID information indicating whether a data type is read-only data, and
the ID information containing a tracking method relating to at least one of a pit and a groove, 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.
