Abstract
Compact-disk players read out some of the redundant table of contents on a compact disk and enter the data in a memory. Since the position of the beam of scanning light is random at the commencement of the read-out and entry process, it can in certain situations take longer for the beam to arrive at the first block (A0) in the table of contents, at which entering is to begin. To decrease the read-out and entry time the beam of light is diverted to the first block (A0) from whatever block it happens to be at at the commencement of the process. In a variant of the process the data are stored commencing with the block that the beam happens to be at at the commencement and ending with the next block with the same content. In a third version the entry commences with the block that the beam happens to be at at the commencement and, when the beam arrives at the last block to be entered, it skips back to the first block (A0) and enters the rest of the data.
