Embodiment approach

[0029] The record carrier status component 32 is used to detect a record carrier update status in which a change is to be made to the information stored on the record carrier. The update status may be based on the real-time performance of the device, such as the number of jumps to real-time file parts or defective and remapped physical addresses. According to one embodiment, the update status is based on the amount of available and used space within the defect management area. For example when a large number of defect management areas are unused and the record carrier is almost full, the record carrier status component may decide to change the allocation of recording areas, increasing user storage space and reducing defect management areas.

[0030] According to one embodiment, the record carrier status means 32 is adapted to detect a succession of blocks having contiguous logical address ranges to be updated for recording in corresponding contiguous physical address ranges. ...

Abstract

A device for recording records information in blocks having logical addresses in a storage space on a record carrier. The device has an interfacing unit (31) for communicating with a host system by exchanging commands and information, a record carrier status unit (32) for detecting a record carrier update status in which information stored on the record carrier is to be changed, and an update unit (33) for initiating an unmount-mount sequence. The unmount-mount sequence is initiated by the device and starts with an unmount process (42) for, via the interfacing means, forcing the host system to relieve control of the record carrier. Then the device has taken control and performs an update process (44) for said changing of information on the record carrier. Finally the control is returned to the host by a mount process (45) that forces the host system to accept the changed information.

Description

technical field [0001] The invention relates to a device for recording information in blocks with logical addresses in a memory space on a record carrier. [0002] The invention also relates to a method for recording information. [0003] The invention also relates to a computer program product for recording information. [0004] The present invention relates to the field of physically organizing recorded data in recording systems, and in particular to defect management when recording real-time information such as video signals. Background technique [0005] A device and method for recording information on a record carrier is known from US6205529. Due to normal use and updating of the stored data files there is a tendency for the data recorded on the record carrier to become fragmented. Defragmentation is used to reorganize stored data so that files are stored in contiguous physical areas. The recording device is controlled by the host system via the interface. The host...
