Method for recording a lead-out on an optical disc

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 (54,61) across two layers is logically interrupted by an intermediate zone (55,56). According to a standardized recording format like DVD the recordi...

Summary: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 (54,61) across two layers is logically interrupted by an intermediate zone (55,56). According to a standardized recording format like DVD the recording area is preceded by a lead-in zone (53) located at the start of the first recording layer and followed by a lead-out zone (64) located at the end of the second recording layer. An outer lead-out part (62) and an inner lead-out part (63) are recorded separated by an unrecorded area (65) 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.
