Zusammenfassung:	FIELD: data carriers. ^ SUBSTANCE: disk has several zones, while each zone has an area for user data for storing user data, and several zones form a group for controlling defects of data carrier, backup area for swapping defects for group is placed on disk, and data about source position for each zone is stored in previously set disk area, while method has following steps: reading of data concerning starting position for each zone, and access to data, on basis of read information concerning source position. ^ EFFECT: higher recording and reproduction stability due to possible processing of larger defects during hot swap, provided by joining several zones within limits of one group. ^ 5 cl, 9 dwg
