Abstract

A method, apparatus, and medium for erasing information recorded on a rewritable recording medium. The method includes: searching for test result information on a recording power recorded on a recording management area disposed on the recording medium; if corresponding test result information is found, reading in the test result information; and by using a recording power determined according to the read test result, recording a unique pattern on at least part of a user data area of the recording medium where predetermined information is recorded. According to the method, the writing characteristic can be greatly improved.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2003-23061 filed Apr. 11, 2003, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a rewritable recording medium, in particular to a method, an apparatus, a computer readable medium and a medium produced therefrom for erasing information recorded on the recording medium. Background technique [0003] In the field of optical recording media, a rewritable digital versatile disc (DVD) market has recently been developing following the introduction of read-only DVDs. Rewritable DVDs include DVD-recordable (DVD-R), which is a write-once disc, rewritable discs such as DVD random access memory (RAM), rewritable DVD (DVD-RW), and another A rewritable DVD (DVD+RW). [0004] All DVD-RAMs, DVD+RWs, and DVD-RWs have a recording film formed as a phase change film. The phase change film has a crystalline structure or an amorphous ...
