METHOD FOR DISCRIMINATING TRACK OF OPTICAL RECORDER/REPRODUCER

PURPOSE: A track discriminating method of an optical recorder/reproducer is provided to improve reliability of a track discriminator by stably discriminating the track even in unstable state of a servo. CONSTITUTION: The method for discriminating a track of an optical recorder/reproducer comprises the steps of: detecting an information in a plurality of sections different from a phase recorded on a head region; verifying whether or not each of the detected signals has a different level; and discriminating the track kind of the sequent data region from the verification resultant. The first step comprises detecting a first head signal(IP1) from the head region at a high position and a second head signal(IP2) from the head region at a low position on the basis of track center of the data region in the head region section. The second step comprises identifying the level of each head signal at the center point of the detected first and second head signals. The third step comprises discriminating the data region by a groove track when the first head signal is at high level, and the second head signal is at low level.
