Abstract
Abstract An information reproducing apparatus for recovering data stored on a recording disc. Table of contents (TOC) data is read from a recorded disc to define the tracks of program material on the recording disc in terms of absolute times which represent each track. A selected track may have a desired order number which is divided into sub tracks, represented by sub absolute times. When a portion of a track is to be read, a search for the sub track permits reproduction of the data on the track from a portion defined by the sub track.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
172 words
An apparatus for reproducing information from a recording medium, comprising: first means for reading TOC data from the recording medium, the TOC data including signals of first absolute start times corresponding to actual tracks on the recording medium respectively and also a signal of a second absolute start time corresponding to a lead-out area of the recording medium; second means for setting sub absolute times between two adjacent absolute start times from the first and second absolute start times; third means for assuming fictitious tracks on the recording medium; fourth means for assigning the sub absolute times to the fictitious tracks respectively; fifth means for designating a desired track out of the fictitious tracks; sixth means for detecting the sub absolute time assigned to the desired track designated by the fifth means; and seventh means for starting reproduction of main information from the recording medium in response to the sub absolute time detected by the sixth means whereby reproduction begins in a location within a track represented by said sub absolute time.
