オ記録再生装置。[Scope of Claim for Utility Model Registration] A rotary head type digital recording medium in which a PCM data area, a SUB area, and an ATF area for tracking are provided on each of a plurality of diagonal tracks to rewrite a portion of a recorded recording medium. In the audio recording and reproducing apparatus, during the writing operation, the signal recorded in the ATF area of the on-track is determined by the crosstalk level difference between the signals recorded in the ATF area of both adjacent tracks obtained by reproducing the ATF area. What is claimed is: 1. A rotary head type digital audio recording and reproducing apparatus, comprising: an ATF error signal generating means for generating an ATF error signal by adding the ATF error signals at a predetermined ratio.
