1. An apparatus for reading a first side and a second side of a dual-sided optical disk, the apparatus comprising:
- an optical disk reader;
a memory operably coupled to the optical disk reader; and
a controller operably coupled to the optical disk reader and the memory, wherein the controller is configured to cause a portion of data from the first side of the optical disk to be (a) read from the optical disk, (b) stored in the memory, and (c) later read from the memory during a time when reading the optical disk is switched from the first side to the second side.

Abstract
An apparatus and method for providing continuous uninterrupted playback of a dual sided optical disk during side-to-side changing of the optical disk. The point at which a dual-sided optical disk will be switched between sides is determined. At some point prior to the switching of sides of the disk, a portion of the data at the end of the first side of the disk is transferred to a memory. During the switching of the disk to the second side, the stored data is read out from the memory to provide uninterrupted continuous playback of the optical disk.

9. An apparatus for reading a first and second side of a dual-sided optical disk, the apparatus comprising:
-
an optical disk reader configured to read the first side of the optical disk while rotating the optical disk in a first direction around an axis and read the second side of the optical disk while rotating the optical disk in a second direction around the axis; a memory operably coupled to the optical disk reader; and a controller operably coupled to the optical disk reader and the memory, wherein the controller is configured to cause a portion of data from the first side of the optical disk to be (a) read from the optical disk, (b) stored in the memory, and (c) later read from the memory during a time when reading the optical disk is switched from the first side to the second side. - View Dependent Claims (10, 11)

12. An optical disk device for providing continuous, uninterrupted playback of a dual-sided optical disk, the optical disk device comprising:
-
an optical reader configured to read the dual-sided optical disk; a memory adapted to store data transferred from the dual-sided optical disk; and a controller configured to determine a portion of data on the first side of the optical disk to be transferred to the memory, wherein the optical reader is configured to read data on the first side of the optical disk up to the portion of data transferred to the memory, the portion of the data transferred to the memory is read while the second side of the optical disk is accessed, and the second side of the optical disk is read after the portion of the data transferred to the memory has been read. - View Dependent Claims (13, 14)
