Embodiment Construction

[0026] FIG. 1 a shows a disc-shaped record carrier 11 having a track 9 and a central hole 10 . The tracks 9, ie the positions of a series of marks representing the information to be (to be) recorded, are arranged in a spiral pattern of turns constituting substantially parallel tracks on the information layer. The record carrier may be optically readable, called an optical disc, and have an information layer of the recordable type. Examples of recordable discs are CD-R and CD-RW, and writable versions of DVD, such as DVD+RW, and high-density writable discs using a blue laser, known as Blu-ray Discs (BD). More details on DVD discs can be found in Reference: "ECMA-267: 120mm DVD-Read-Only Disc (1997)". Information is represented on the information layer by recording along the track optically detectable marks (eg crystalline or amorphous marks in a phase change material). The track 9 on the recordable type record carrier is represented by a pre-embossed track structure provided ...

Abstract

A device for recording records information in blocks having logical addresses at a physical address (52) in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information, such as remapping tables, maintained in defect management areas. For avoiding remapping of real time information, such as video, a series of blocks (42) having a continuous logical address range is recorded in a corresponding allocated physical address range. In the event of a defect interrupting the allocated physical address range local offset information is generated for adding an offset to a local range of physical addresses in said address translation for skipping (61) the defect. The blocks logically following the last block before the defect are written at physical addresses following the defect, and an end portion (62) that extends beyond the allocated physical address range due to the defect, is accommodated elsewhere.

Description

technical field [0001] The invention relates to a device for recording information. [0002] The invention also relates to a device for reading information. [0003] The invention also relates to a method for recording information. [0004] The invention also relates to a computer program product for recording information. [0005] The present invention relates to the field of defect management in recording systems, and in particular to defect management in the continuous recording of real-time information such as video. Background technique [0006] A device and method for recording information on a record carrier is known from WO 01 / 06512, wherein digitally compressed video data is recorded on an optical disc according to a video coding standard (eg MPEG2 format). The device has input means for receiving video information, and recording means for recording video information within a stream of blocks having a contiguous logical address range in a physical address range a...
