Abstract
A recording and/or playback apparatus and method and a method of moving tracks, and more particularly, an apparatus and method for efficiently seeking a track and recording and/or playback data on/from a recording medium, are disclosed. The method of moving tracks includes changing a gap between a lens part and a recording medium in correspondence with a distance of moving tracks when the lens moves from a current track to another track. Accordingly, it is possible to minimize or prevent the collision between the lens part and the recording medium and to efficiently seek the track to perform recording/reproduction when recording and/or playback data on/from the recording medium.
Claims33
A method of moving tracks comprising:
- changing a gap between a lens and a recording medium in correspondence with a distance of the moving tracks while the lens moves from one track to another.
A method of moving tracks comprising:
- changing a gap between a lens and a recording medium to a predetermined level and horizontally moving the lens from a track to another track,
- wherein the gap between a lens and a recording medium is changed stepwise.
A recording and/or playback method comprising:
- controlling a gap between a lens and a recording medium to be uniform, using a control signal,
- wherein the gap is changed by applying an offset corresponding to a distance of moving tracks to the control signal while lens part moves the tracks.
A method of recording and/or playback data on/from a recording medium, the method comprising:
- (a) changing a gap between a lens and the recording medium to a first level and moving the lens to a target track while moving tracks;
- and
- (b) changing the gap to a second level and minutely moving the lens or the optical pickup from a reached track to the target track while a track is counted.
A recording and/or playback apparatus comprising:
- a pickup including a lens and irradiating a light beam emitted from a optical source onto a recording medium;
- a gap servo controlling a gap between the lens and the recording medium using a gap control signal generated by the light beam reflected from the recording medium;
- and
- a controller applying an offset corresponding to a distance of moving tracks to the gap control signal and changing the gap while lens part moves the tracks.
