摘要： The invention relates to a method and recording device for selecting an optimal write strategy for a specific type of optical recording disk. Such an optimal write strategy is selected even when the optical recording disk is of a type that has not been previously encountered or when the optical recording disk is otherwise unrecognized by an optical disk drive. The optimal write strategy and associated settings are selected from a set of write strategies stored in a disk drive. The disk drive bases its selection of the write strategy on the performance results of test writings conducted on the optical disk. The method entails testing the write strategies first at the maximum possible write speed and if necessary, at successively lower speeds until a write strategy that achieves a minimum acceptable write quality is identified or until the minimum write speed is reached. The selected optimal write strategy may be stored in the recording device or, alternatively, on the optical recording disk itself.

摘要： The present invention relates to determining an optimized write power used for writing electronic data on optical disc and includes a method, a device and a computer program product for determining a write power for writing electronic data on a medium (32, 108), based on a sequence of written data, using a power control model, which includes a written data deviation measure, a written data asymmetry and a written data asymmetry target value, the method comprising the steps determining the written data deviation measure for the sequence of written data (step 202), adjusting the written data asymmetry target value in relation to the written data asymmetry, if the written data deviation measure has changed (steps 218, 220, 226, 228), determining the write power in dependence on written data asymmetry (step 210), and writing another sequence of data on the medium using said determined write power (step 212), so as to obtain power optimized writing of data.

摘要： 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 signal, a method for seamless linking of 2 parts of a recording on a CD-R/CD-RW disk is described. Recording the modulated signal is started at a location dependent on the location of an end part of said earlier recorded information signal, while locking said recording clock speed to the track wobble. Interruption of a recording can be done without loss of data or loss of storage capacity. No difference between uninterrupted and interrupted recording is guaranteed for the play-back system.
