1. A method for reading a first and second side of a dual sided optical disk comprising:
- determining a point when reading said dual sided optical disk should be switched from said first side to said second side;
storing a portion of data from said first side of said dual sided optical disk in a memory, said portion of data comprising data from said determined point on said first side of said dual sided optical disk up to an end of said first side of said dual sided optical disk;
reading data from said first side of said dual sided optical disk;
switching said reading of said dual sided optical disk from said first side to said second side when said determined point has been reached; and
reading said data from said first side of said dual sided optical disk stored in said memory while said switching is occurring.

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.

14. A method for providing uninterrupted continuous playback of data read from a first and second side of a dual sided optical disk comprising:
-
storing a portion of data from said first side of said dual sided optical disk in a memory;
reading data not included in said portion of data stored in said memory from said first side of said dual sided optical disk;
reading said portion of data stored in said memory after reading said data not included in said portion of data stored in said memory;
switching said dual sided optical disk from said first side to said second side concurrently with said reading said portion of data stored in said memory; and
reading data from said second side of said dual sided optical disk after reading said portion of data stored in said memory. - View Dependent Claims (15, 16, 17, 18, 19)

20. An apparatus for reading a first and second side of a dual sided optical disk comprising:
-
an optical disk reader;
a memory connected to said optical disk reader; and
a controller connected to said optical disk reader and said memory, said controller causing a portion of data from said first side of said disk to be read from said disk and stored in said memory and later read from said memory during a time when reading said disk is switched from said first side to said second side, thereby providing uninterrupted continuous playback of said dual sided optical disk.
