    摘要: The apparatus is suitable for managing a data carrier (1) obtaining a fast data transfer from it to the apparatus when the carrier is driven with a constant angular velocity (CAV). It comprises a motor (3) for driving the carrier, an optical head having light source (16) for reading and/or writing data stored form and in it. Furthermore, it comprises means, involving a processor set (50) for determining the frequency of the use of files contained in the data carrier, such that the more frequently used ones are put in a location for a faster transfer. While the transfer is being performed, the motor and the light source arc stopped so that supply energy is economized, which is interesting for a battery-operated apparatus. Application: The invention is well suited for small size R/W optical discs (SFFO).

    摘要: A method is described for writing an optical disc (2) having a user storage space (USS). The method comprising the steps of determining a reserved storage section (VRSS 80) of the user storage space (USS) for use by a specific application;—determining which parts (81) of said reserved storage section (VRSS 80) are free for writing, i.e. not occupied;—allocating all addresses in those free parts (81) to a reservation file (VRF).

    摘要: 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 storing first file system data and second file system data addressing user data in a user area (UA) on the medium. The control means (20) are adapted to define partitions for both file systems such that the partitions start at the same location and to store the second file system directory entries outside the first file system partition. This reduces time and space necessary for handling the second file system data by allowing two file systems to share their file entries, while protecting the second file system directory entries from being erased when the medium is under control of the first file system.

    摘要: Disclosed is a record carrier, in particular a recordable or rewritable optical disc, having a program memory area for storing administrative data, a lead in area, a program area for storing user data and a lead out area. In order to enable a drive to access digital rights management data which are stored in the program area, comprising e.g. usage rights and cryptographic keys, it is proposed that the record carrier further comprises:—a DRM pointer entry (ALP) comprising the entry point for said digital rights management data is stored in the program area after said digital rights management (DRM) data, —a drive-readable entry comprising an information allowing the drive to find said DRM pointer entry (ALP) and to access said digital rights management (DRM) data is stored in said program area or said program memory area.

    摘要: A method is described for writing an optical disc (2) having a user storage space (USS). The method comprising the steps of dividing the storage space of an optical disc (2) into, on the one hand, one or more sections (80; 181, 182, 183, 184) where an application is allowed to write and, on the other hand, one or more sections where it is not allowed to do so. The location and extent of the allowed section(s) is either fixed in format or determined by one or more parameters (BA, L, VAPT) stored on disc. A signal processing system (120) of a video recorder apparatus (100) is designed, before attempting a write operation to a disc (2), to determine the allowed storage area (VASS) for the present disc, and to select free area (72) for writing only within the allowed storage area.
