Abstract RU 2359344 C2

FIELD: physics, computer engineering.

SUBSTANCE: information medium, device and method for record/reproduction are suggested. Information medium comprises several levels of record. Every layer includes area of user data and middle area. Middle area is expanded during finalisation of information medium. As a result, if middle area of disk is not big enough, then it may be expanded in flexible manner, therefore it provides for better mode of record.
