Abstract
A decoder is provided which, in parallel with decoding into TOC information from sub-Q data read out from the lead-in area of an optical disk, decodes into TEXT information from sub-R-W data read out and determines whether the TEXT information is present based on the sub-R-W data. The decoder, while decoding into plural packs of TEXT information, performs error detection on the decoded-into TEXT information based on error detection codes included in the respective packs, and sends to a microcomputer, if a result of the error detection is normal, a first data set consisting of corresponding decoded-into header information and TEXT content and, if a result of the error detection is not normal, a second data set which is of the same data size as the first data set and which is an indication code indicating that the result of the error detection is not normal.
