Abstract
This document relates to a method capable of reducing transfer errors of a sled motor for moving an optical pickup to the outer circumference when labels are recorded on a disc. An optical disc recording method may comprise checking a step pattern having a small transfer error in the sled motor, and recording labels on a label plane of an optical disc while driving the sled motor based on the checked step pattern. Step patterns can be classified based on a structure of the sled motor or a unit for driving the sled motor. The step patterns having a small transfer error can be detected in a process of manufacturing an optical disc apparatus and stored in memory of the optical disc apparatus.
Claims14
An optical disc recording method, comprising:
- checking a step pattern having a small transfer error in a sled motor;
- and
- recording labels on a label plane of an optical disc while driving the sled motor based on the checked step pattern.
An optical disc apparatus, comprising:
- an optical pickup configured to read data from a data plane of an optical disc and record data on the data plane or a label plane of the optical disc;
- a sled motor configured to move the optical pickup to an inner or outer circumferences;
- memory configured to store step patterns having a small transfer error in the optical pickup resulting from the sled motor;
- and
- a controller configured to search the memory for a step pattern having a small transfer error and drive the sled motor based on the retrieved step pattern such that labels are recorded on a label plane of an optical disc.
