AI Technical Summary

Benefits of technology

Enables accurate detection and resumption of the recording process at the failure position, ensuring stable label printing on LightScribe discs without tracking guide signals, overcoming the limitations of sequential recording.

Problems solved by technology

However, because wobble lands / grooves are not formed on the label side of the disc, it is not possible to perform a tracking servo control process, nor is it possible to randomly access a portion of the disc.
Accordingly, when a recording or printing process on a label surface fails due to unstable servo control, a disc medium problem, a buffer under run, etc., the recording failure position cannot be located so the label recording process also fails.

Embodiment Construction

[0024]Preferred embodiments of a recording method for an optical disc device in accordance with the present invention will now be described in detail with reference to the accompanying drawings.

[0025]FIG. 3 is a block diagram of an embodiment of an Optical Disc Device (ODD) in which a recording method in accordance with the present invention is implemented. As shown, the ODD includes an optical pickup 20, a digital recording signal processor 30a, a digital playback signal processor 30b, a channel bit encoder 40, an optical drive 41, an R / F unit 50, a servo unit 60, a drive unit 61, a counter 12, a spoke detector 13, a memory 71, and a microprocessor 70. Also included are a spindle motor 11 and a sled motor 21.

[0026]The digital recording signal processor 30a adds an error correction code (ECC) or the like to input digital data to convert the data into a recording format. The channel bit encoder 40 then converts the data into a bitstream. Further, the optical drive 41 outputs a drive ...

Abstract

An optical disc device recording method, which includes determining whether or not a recording process that records information on a label surface of an optical disc has failed, detecting a recording failure position at which the recording process has failed when the determining step determines the recording process has failed, and resuming the recording process from the detected recording failure position.

Description

[0001]This application is a continuation of co-pending application Ser. No. 11 / 411,100, filed on Apr. 26, 2006, the entire contents of which are hereby incorporated by reference and for which priority is claimed under 35 U.S.C. §120; and this application claims priority of Application No. 10-2005-0034306 filed in Korea on Apr. 26, 2005 under 35 U.S.C. §119.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a recording method for an optical disc device, and more particularly to a recording method which allows for the resumption of a recording process from a recording failure position on an optical disc such as a LightScribe disc having no tracking guide signal.[0004]2. Description of the Related Art[0005]The LightScribe disc is an optical disc on which not only data can be recorded on a data surface, but also on which a label with a desired design can be printed on a label surface. A layout of the label surface of the LightScribe disc is ...
