ABSTRACT:
A method of recording information stores lead-out information on a multilayer record carrier of an opposite track path type. A two part recording area across two layers is logically interrupted by an intermediate zone. The recording area is preceded by a lead-in zone located at the start of the first recording layer and followed by a lead-out zone located at the end of the second recording layer. An outer lead-out part and an inner lead-out part are recorded separated by an unrecorded area and together constituting the lead-out information on the second recording layer. The inner lead-out part covers a predefined radial position range corresponding to a range of radial positions used by reading devices for accessing the second recording layer during a disc loading procedure. The outer lead-out part is recorded at the end of an area of the second recording layer containing user information.
