Embodiment Construction

[0045] FIG. 1 a shows an example of a recording medium 11 having the shape of a disc with tracks 9 and a central hole 10 . Tracks 9 as positions of a series of (to-be) recorded marks representing digital information signals (data) are arranged on the information layer in a spiral pattern of turns constituting substantially parallel tracks. The recording medium may be optically readable, called an optical disc, and have a recordable type of information layer. Examples of recordable discs are CD-RW, and writable versions of DVD, such as DVD+RW, and high-density rewritable discs using blue lasers, called Blu-ray Discs (BD). Digital information signals (data) are represented on the information layer by recording optically detectable marks along the track, for example crystalline or amorphous marks in a phase change material. The track 9 on the recordable type recording medium is represented by a pre-embossed track structure provided during manufacture of the blank recording mediu...

Abstract

A recording apparatus for recording digital information signals on a removable rewritable disc like recording medium has been proposed. The apparatus comprises writing means (21, 22, 25) for recording the digital information signals and control means (20) for controlling the recording. The apparatus is capable of performing initialization, formatting and defect management of a rewritable medium. Further, the apparatus is capable of storing first file system data in a user area (UA) and second file system data in a general application area (GAA) on the medium. The control means (20) are adapted to modify defect management data on the medium in order to block write access to UA under control of the first file system. This prevents systems unaware of the second file system data on the medium from modifying contents of UA.

Description

technical field [0001] The present invention relates to a recording apparatus for recording digital information signals on a removable and rewritable disc type recording medium, said medium comprising a user area with user data represented by the digital information signal and including The table area of ​​the defect table, the defect table includes defect management data with a predetermined data format, the defect management data is related to the defect area in the user area and the replacement area on the medium, and the recording device includes: [0002] an input device for receiving digital information signals; [0003] recording means for recording digital information signals on a medium; [0004] a reading device for reading recorded digital information signals recorded on the medium; [0005] an output device for outputting the read digital information signal; [0006] A control device for controlling recording of digital information signals. [0007] The inventi...
