Device for recording recordable media and method

Abstract

The invention relates to a device for recording recordable media, for example recordable DVD media types, a number of which is currently available in the market. Upon receipt of a medium and assessment that the medium is a recordable medium, the device attempts to recognize it, i.e. to recognize its media type. If the recordable medium is not recognized, a reading operation is anyway performed. In this way it is left open the possibility to access recordable media belonging to a recordable media type unknown to the device but from which the device can nevertheless read, e.g. a newly introduced media type belonging to a media family known to the device. If applied to a device for recoding DVD, the invention makes it possible to read from a DVD+R9 medium. The invention further relates to a method for accessing a medium.

Description

technical field [0001] The invention relates to an apparatus for recording a recordable medium and a method for accessing the medium. Background technique [0002] An example of a device of the type described above is a DVD recorder, such as any currently available on the market, like for example Philips' DVDR75 type, which is a DVD+RW recorder. [0003] Media currently available on the market belong to several recordable DVD media types (also referred to as "formats"): DVD-R, DVD-RW, DVD+R, DVD+RW, which all belong to the DVD media family, That is, both recorded and finalized media can be read by a DVD-ROM player. A recordable DVD medium is said to be finalized when a predetermined table representing the content of the medium has been recorded at a fixed location on the medium, such as according to the DVD-ROM standard. [0004] Such known DVD recorders are capable of recording on media belonging to the recordable DVD media types DVD+R and DVD+RW, and are able to read med...

AI Technical Summary

Problems solved by technology

The first reason is that the access done on a medium depends somewhat on the type of media said medium belongs to, thus requiring specialized software modules and sometimes utilizing different hardware features, so DVD recorders due to software / hardware Restriction does not allow easy access to certain media types

[0006] The second reason is that certain formats are competing among these formats and thus a DVD recorder manufacturer may decide to design a DVD recorder to privilege certain formats by supporting them and using them by not supporting others. Other formats are at a disadvantage

[0008] Disadvantage: Known DVD recorders can only access media with the corresponding functional group based on the identification of the media type
