Embodiment Construction

[0082] The present invention will be described below by way of illustration with reference to the accompanying drawings.

[0083] An information recording and reproducing apparatus capable of mounting an information recording medium according to the present invention obtains a recording condition by performing recording adjustment processing using a parameter calibration area. In one embodiment, the obtained recording conditions are recorded on an information recording medium. The recording condition recorded on the information recording medium is read out for execution of the next cycle of adjustment processing, and can be used to obtain a new recording condition.

[0084] Here, the recording conditions refer to operating conditions of the optical disc device used when the optical pickup device records information on an optical disc. The recording condition is obtained from the reproduction state of the recording condition information.

[0085] The recording conditions incl...

Abstract

An information recording medium includes a data recording area for recording data; and a parameter calibration area for recording recording condition information. The parameter calibration area includes a used area having the recording condition information recorded therein, an unused area having no recording condition information, and a border area for recording distinguishing information for distinguishing a border between the used area and the unused area. The border area is between the used area and the unused area.

Description

technical field [0001] The present invention relates to an information recording and reproducing method and an information recording and reproducing apparatus. In particular, the present invention relates to a method for recording information for distinguishing a boundary between an area which has been used for adjustment in a parameter calibration area in which recording information is to be recorded and an area which has not been used for adjustment. An information recording medium, an information recording and reproducing method, and an information recording and reproducing apparatus. Background technique [0002] As a circular information recording medium, an optical disc is known. Recently, as the recording density and capacity of optical discs have increased, it is becoming important to ensure high reliability of optical discs. In order to ensure high reliability, an optical disc device performs adjustment processing for obtaining recording conditions used when recor...
