US 6,856,585 B2 · Method and device for recording information in units

Abstract

A method and device for recording information signals on a partly recorded writable record carrier (11), e.g. an optical disc. An information signal represents at least one information unit. The record carrier has a recording track which comprises preformed track position information indicative of locations for recording the information units. From the information signal a modulated signal is generated, and the recording track is scanned for recording the modulated signal. If recording is after and adjacent an existing recorded unit, linking information is read from an end boundary area of the existing recorded unit and used for logically generating the modulated signal. If recording is before and adjacent to an existing unit, linking information is read from a begin boundary area of the existing unit and thereafter used for logically generating the modulated signal.

Method of recording at least one information unit on a record carrier having a recording track which comprises preformed track position information indicative of predefined locations for recording information units and a first one of said locations comprising an earlier recorded information unit, said method comprising:

(a) generating a modulated signal representing the at least one information unit, and
(b) scanning the recording track and recording the modulated signal at a second one of said locations, characterized in that the method comprises:
(c) in the event that the second one of said locations is after and adjacent to the first one of said locations, reading linking information from an end boundary area of said first one of said locations and using the linking information other than synchronization information for logically generating contents of the modulated signal.

Device for recording at least one information unit on a record carrier (11) having a recording track (9) which comprises preformed track position information indicative of predefined locations for recording information units and a first one of said locations comprising an earlier recorded information unit, said device comprising:

modular means (29) for generating a modulated signal representing the at least one information unit, and
recording means (22) for scanning the recording track and recording the modulated signal at a second one of said locations,
characterized in that the device comprises retrieving means (20, 30) for reading linking information from an end boundary area of the location preceding the second one of said locations and in that the modulator means comprise linking means (31) for using the linking information other than synchronization information for logically generating contents of the modulated signal in the event that the second one of said locations is after and adjacent to the first one said locations.
