Abstract
Various apparatuses and methods for laser positioning in an optical disc drive are provided. In one embodiment, a laser positioning apparatus is provided in which an assembly is employed to position a first laser beam generated by a first laser relative to a first side of an optical disc site in the optical disc drive. Also, a structure is coupled to the assembly and configured to extend around an edge of the optical disc site to a second side of the optical disc site. The structure positions a second laser beam generated by a second laser relative to a second side of the optical disc site based upon a movement of the assembly.
Claims22
An apparatus for laser positioning in an optical disc drive, comprising:
- an assembly that positions a first laser beam generated by a first laser relative to a first side of an optical disc site in the optical disc drive;
- a structure coupled to the assembly and configured to extend around an edge of the optical disc site to a second side of the optical disc site;
- and
- a second laser configured to generate a second laser beam, the structure positioning the second laser beam relative to a second side of the optical disc site based upon a movement of the assembly.
An optical disc drive, comprising:
- a first laser;
- a second laser;
- an assembly that positions a first laser beam generated by the first laser relative to a first side of an optical disc site in the optical disc drive;
- a control system that controls the operation of the assembly;
- a structure coupled to the assembly and configured to extend around an edge of the optical disc site to a second side of the optical disc site;
- and
- a second laser configured to generate a second laser beam, the structure positioning the second laser beam relative to a second side of the optical disc site based upon a movement of the assembly.
An optical disc drive, comprising:
- means for generating a first laser beam;
- means for generating a second laser beam;
- means for positioning the first laser beam relative to a first side of an optical disc in the optical disc drive;
- and
- means for positioning the second laser beam relative to a second side of the optical disc based upon the positioning of the first laser beam.
A method for laser positioning in an optical disc drive, comprising the steps of:
- generating a first laser beam with a data side laser;
- generating a second laser beam with a label side laser;
- manipulating an assembly to position the first laser beam relative to a first side of an optical disc in the optical disc drive;
- and
- positioning the second laser beam relative to a second side of the optical disc based upon the manipulation of the assembly.
