A digital recording disk, such as an audio or a video disk, has a central bearing area, a data medium layer having at least one data track thereon, and a protective layer covering a face of reading of said disk, said protective layer is provided with damages, causing disturbances during a reading operation. Said damages are repaired by removing the protective layer in a section between a central bearing area and a circumferential edge of said disk to a level at which disturbances during reading do not appear. Said removing of said protective layer is carried out in directions cutting across the data track path.
