Abstract
PURPOSE:To enable a supplier to make the characteristic test of an optical disk medium which accompanies the process of writing to the data part of the sectors assigned for the supplier by forming the sector constituted by putting the information indicating whether the sector is for a user or the supplier to a header part and assuring the optional sector or track on the optical disk medium as the sector or track for the supplier. CONSTITUTION:The information discriminating whether the sector is for the user or the supplier is recorded into the discrimination header part preformatted for every sector, so that the supplier of the medium can use the tracks or the sectors of every other optional number. For example, a FLAG 4 is a pattern to discriminate whether this sector is for the user or the supplier. This pattern enables the supplier to make the characteristic test accompanying the writing test in arbitrarily dispersed places.
