OPTICAL INFORMATION RECORDING MEDIUM, APPARATUS FOR RECORDING INFORMATION, APPARATUS FOR REPRODUCING INFORMATION, METHOD OF RECORDING INFORMATION, METHOD OF REPRODUCING INFORMATION AND METHOD OF MAKING INFORMATION RECORDING MEDIUM Russian patent published in 2014 - IPC G11B20/10 

FIELD: physics, computer engineering.

SUBSTANCE: invention discloses an optical data storage medium, a method for production thereof, methods of recording and producing information and apparatus for recording and reproducing information. The medium has a control region in which control information is stored. The control information includes a format number which provides information on the type of recording strategy and type of pre-compensation during recording, and a recording strategy parameter which provides information on the size of the position shift of the edge or change in pulse width in the recording pulse series for forming a record label. The value of the format number is varied according to the combination of the type of recording strategy and the type of pre-compensation during recording.

EFFECT: making a recording medium containing information on the recording strategy and pre-compensation during recording for high-density recording.
