Optical disc apparatus accessing method and system therefor

摘要

There are provided a plurality of information recording surfaces to be reproduced on one side of an optical disc to be reproduced, and when accessing control of an optical pickup over a plurality of recording layers is performed, first, a beam focal point of the optical pickup is moved using a moving means to the recording layer on which target information is recorded to thereby perform switching processing of information recording layers during reproduction, after which accessing control of the optical pickup is performed using control processing means similar to the access between the same recording layers, and with respect to the pausing operation, in a layer in which information is recorded from the inner circumference to the outer circumference, one track jumping is repeated toward the inner circumference, while in a layer in which information is recorded from the outer circumference to the inner circumference, one track jumping is repeated toward the outer circumference.
