Method of determining the type of an optical disc and a data recording and/or reproducing apparatus

Abstract

A method of determining an optical disc type and a data recording and / or reproducing apparatus. The method of determining the type of an optical disc loaded in a data recording and / or reproducing apparatus includes reading optical disc type determination order stored in a memory (3) included in the data recording and / or reproducing apparatus in order to determine a type of the optical disc from a plurality of optical disc types, and controlling a read / write unit (1) in the data recording and / or reproducing apparatus according to the determination order to determine the type of the optical disc. According to the present invention, an optical disc using pattern of users, optical disc using frequency according to type, and a point of time in which an optical disc is used are considered to change an order for optical disc type determination to allow to rapidly determine the type of a loaded optical disc.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2004-0063758 filed with the Korean Intellectual Property Office on Aug. 13, 2004, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to a method of determining the type of an optical disc and a data recording and / or reproducing device. Background technique [0003] There are various types of information storage media on which information is stored. Such media include: magnetic disks, such as floppy disks and hard disks; semiconductor memory chips, such as ROM or RAM; and optical disks, on which data is recorded using laser light. [0004] Optical discs are very widely used because they have a large information storage capacity and their cost is relatively low. According to the information storage capacity in an optical disc, it is classified into a compact disc (CD), a digital versatil...

AI Technical Summary

Problems solved by technology

By reproducing the data recorded in the lead-in area of ​​the loaded optical disc, the type of the optical disc must be identified, but there is a problem that the data recording and / or reproducing apparatus may reproduce data before recognizing the type of the loaded optical disc.
