Abstract
An optical recording medium that includes a wobbled track including a wobble signal and a wobbled header track including a wobble header signal containing header information. Accordingly, the physical geometry of a header area is uniform so that a decrease in the quantity of light reflected from the optical recording medium can be prevented when data is recorded to the recording medium.
Claims58
An optical recording medium comprising:
- a wobbled track comprising a wobble signal;
- and
- a wobbled header track comprising a wobble header signal comprising header information.
A method of recording data to a recording medium which comprises a wobbled track comprising a wobble signal and a wobbled header track comprising a wobble header signal containing header information, the method comprising:
- recording data to the wobbled track with a predetermined recording power;
- and
- passing the wobbled header track with a passing power which is lower than the recording power by a predetermined value.
An apparatus to record/reproduce data on/from a recording medium which comprises a wobbled track comprising a wobble signal and a wobbled header track comprising a wobble header signal comprising header information, the apparatus comprising:
- a recording unit to record the data to the wobbled track with a predetermined recording power, and to pass the wobbled header track with a passing power which is lower than the recording power by a predetermined value.
A computer readable medium encoded with processing instructions for implementing a method of recording data to a recording medium which comprises a wobbled track comprising a wobble signal and a wobbled header track comprising a wobble header signal containing header information performed by a computer, the method comprising:
- recording data to the wobbled track with a predetermined recording power;
- and
- passing the wobbled header track with a passing power which is lower than the recording power by a predetermined value.
An optical recording medium comprising:
- a first modulated signal disposed in a track;
- and
- a second modulated signal comprising header information referring to the track.
A method of recording information to a recording medium, comprising:
- recording the information to a track of the optical recording medium;
- and
- detecting a flag in the track during said recording so as to not record information onto an area containing header information.
