Abstract
An information recording device (1) is provided with a recording element (501) for recording information in an information recording medium (100) wherein pre-information (LPP) is previously recorded for controlling recording of recording information, by irradiating laser beams (LB) of a prescribed power, and a control element (504) for controlling the recording element to record the recording information with a power which permits a first reproduction quality (AR characteristic), which is a pre-information reproduction quality, to satisfy a prescribed first standard.
Claims15
An information recording apparatus comprising:
- a recording device for recording record information, by irradiating laser light having a predetermined power, onto an information recording medium on which pre-information for controlling the recording of the record information is recorded in advance;
- and
- a controlling device for controlling said recording device to record the record information with such the power that first reproduction quality, which is reproduction quality of the pre-information, satisfies a predetermined first reference.
An information recording method comprising:
- a recording process of recording record information, by irradiating laser light having a predetermined power, onto an information recording medium on which pre-information for controlling the recording of the record information is recorded in advance;
- and
- a controlling process of controlling the power to record the record information with such the power that first reproduction quality, which is reproduction quality of the pre-information, satisfies a predetermined first reference.
A computer program product in a computer-readable medium for tangibly embodying a program of instructions executable by a computer provided in an information recording apparatus, said computer program product making the computer function as at least one portion of a recording device and a controlling device,
- said information recording apparatus comprising:
- said recording device for recording record information, by irradiating laser light having a predetermined power, onto an information recording medium on which pre-information for controlling the recording of the record information is recorded in advance;
- and
- said controlling device for controlling said recording device to record the record information with such the power that first reproduction quality, which is reproduction quality of the pre-information, satisfies a predetermined first reference.
