Problems solved by technology

In this case, the recorded signal cannot be reproduced correctly
[0056] In addition, the lens shift of the objective lens 117 has been described as a main factor of the deviation of the information recording position; however, the disc tilt also causes the deviation of the information recording position

Abstract

A recording apparatus includes: a light illumination and light sensing unit configured to illuminate an optical disc recording medium including a reference surface having address information recorded and a recording layer, with recording light and light for position control; a recording unit which performs recording on the recording layer; and a control unit which controls, when data instructed to be recorded is to be recorded from an instructed recording start address, the recording unit to perform recording of dummy data on an area adjacent to a front side at least from the recording start address over a range of equal to or greater than the maximum spot deviation amount between an illumination spot of the light for position control and an illumination spot of the recording light and to perform recording of the data instructed to be recorded in succession to a recorded area of the dummy data.

Description

technical field [0001] The present invention relates to a recording device and a method thereof, the recording device is configured to irradiate an optical disc recording medium with recording light and position control light through a common objective lens, the optical disc recording medium has a reference surface and a recording layer on which the reference surface is passed A position guide element is formed to record address information, the recording layer is formed at different depth positions from a reference surface, the recording light is used to perform mark recording on the recording layer, and the position control light is used to perform mark recording according to the position formed on the reference surface. The position guide element to perform position control. Background technique [0002] As an optical disc recording medium (optical disc) for recording and reproducing signals by light irradiation, for example, CD (Compact Disc), DVD (Digital Versatile Disc...
