Abstract
Proper operation of a recording and reproducing apparatus is verified by comparing, after a suitable delay, error detection codes calculated for compressed data prior to being recorded on a medium with error detection codes calculated for the corresponding compressed data reproduced from the medium, thereby reducing the amount of delay memory needed to temporarily store the error detection codes calculated prior to recording of the data.
