TRACKING SERVO CONTROL PATTERN OF AN OPTICAL INFORMATION RECORDING MEDIUM AND A TRACKING SERVO CONTROL METHOD USING THE SAME

摘要

PURPOSE: A tracking servo control pattern of an optical information recording medium and a tracking servo control method using the same are provided to perform tracking servo control without affecting the recording/reproducing of optical information.;CONSTITUTION: A tracking servo control pattern(SP) of an optical information recording medium has a reference reflection pattern(R) and a servo reflection pattern(A). The reference reflection pattern indicates a start position of tracking servo control by reflecting light. The servo reflection pattern is apart from the reference reflection pattern in the tracking direction and reflects the light which has passed through the reference reflection pattern at different time intervals according to the incidence position of the light.;COPYRIGHT KIPO 2010
