FIELD: information technologies.
SUBSTANCE: optical environment of information storage contains an input area, a user data area and an output area. The input area contains the first area, having the first pitch of a path, the second area having the second pitch of a path, differing from the first pitch of a path, and a transition area arranged between the first area and the second area. Information related to a disk is recorded in the first area.
EFFECT: provision of possibility to smoothly reproduce data from optical environment of information storage with lower frequency of errors generation, compatibility with existing optical environments of information storage.
