Problems solved by technology

However, adapters and stand-alone server filesystems are quite complex, and moreover, adapters need to be set up to couple with standard storage devices, mainly hard disks, and metadata needs to be controlled in accordance with the capabilities of server filesystems only combined with such standard devices. Storage in Non-Volatile Memory
The problem with this is that the performance of the server file system is not optimal for a particular type of storage device

Embodiment Construction

[0017] figure 1 A storage device for a removable record carrier is shown. A storage device 42 for recording and retrieving blocks of information is indicated by dashed lines and is coupled via a data interface 43 to a user data processing device 41 , eg a host computer. A record carrier 11 is schematically shown in device 42, said record carrier being removable and being replaceable by a different record carrier, eg an interchangeable hard disk cartridge or an optical disc. The information blocks are to be stored in a recordable area on the record carrier. The device has a data interface unit 44 for receiving commands, in particular write and read commands, and for transferring information blocks to the host 41 . Information blocks include user data blocks and metadata blocks. A metadata block contains file management information formatted according to a file management system (FS), usually a UDF (see available from www.osta.org A standard file system such as the Universa...

Abstract

A storage device for recording and retrieving information blocks on a removable record carrier is described. Via an interface ( 44 ) the device receives commands, user data blocks and meta data blocks comprising file management information. The device has a non-volatile memory ( 31 ), a meta data block detection unit ( 47 ), and a control unit ( 20 ). The device temporarily stores the meta data blocks in the non-volatile memory until detecting an update condition, e.g. an eject command. The update condition indicates that the removable record carrier is to be updated to a state in which the record carrier is usable in a different storage device. In the event that the update condition has been detected the meta data blocks are transferred from the non-volatile memory to the record carrier ( 49 ).

Description

technical field [0001] The invention relates to a storage device for recording and retrieving blocks of information. [0002] The invention also relates to a method of storing blocks of information. [0003] The invention also relates to a computer program product for storing blocks of information. Background technique [0004] US6219693 discloses an apparatus and method for storing information on a record carrier. The document discloses an archive storage structure, including a file system distributed on a data processing platform, and the platform is composed of a host coupled with an adapter through a data interface. The adapter is equipped with input / output subsystem and non-volatile memory. The adapter is coupled to at least one standard storage device such as a hard disk via a second data interface. The subsystems independently perform the tasks of the local file management system. The distributed nature of the structure makes it possible to implement the file sys...
