Patent ID: 7286447

Claim:
A method of controlling an apparatus for recording or reproducing information on/from a disc having a wobbled track, the method comprising: wherein the error compensation signal is generated by monitoring the extracted characteristic, including an amplitude of the wobble signal, and fixing the error compensation signal as the determined error compensation signal in response to the amplitude of the wobble signal being substantially at a maximum level detecting a wobble signal recorded on the wobbled track from the disc for error compensation; and removing an error component occurring during a recording or reproducing operation, based on the wobble signal, where the removing of an error component comprises: extracting at least one characteristic of the wobble signal among a jitter, an error rate, an envelope, and a peak value of the wobble signal; changing a predetermined error compensation signal to determine an error compensation signal corresponding to an optimal characteristic value or an optimal characteristic signal of the extracted characteristic of the wobble signal; and generating an error compensation signal corresponding to the determined error compensation signal to remove the error component, based on the optimal characteristic value or the optimal characteristic signal of the extracted characteristic of the wobble signal, and wherein the generating of the error compensation signal comprises: monitoring the extracted characteristic, including an amplitude of the wobble signal; and fixing the error compensation signal as the determined error compensation signal in response to the amplitude of the wobble signal being substantially at a maximum level.
