  • Reading and writing of information blocks
    Patent number: 7616546
    Abstract: A system writes and reads information blocks on a record carrier and generates status information which is indicative of the fact that at least one area of the record carrier has been written. The status information includes initial-area information which is indicative of an uninterrupted written initial area which extends from the start of a track pattern area intended for writing information blocks. The status information may be fixed on the record carrier.

  • Writing device, record carrier and method of writing information blocks, and reading device for reading information blocks
    Publication number: 20030156522
    Abstract: Reading a partly written writable record carrier having a track structure for positioning the write head above unwritten areas of the track pattern by means of a reading device which positions the read head on the basis of written marks, yields problems when an isolated information block after an unwritten area must be read. A system is disclosed for writing and reading information blocks on a record carrier of a writable type such as a CD-RW or a DVD-RAM. The writing device is provided with status means for generating status information which is indicative of the fact that at least one area of the record carrier has been written, while the status information comprises initial-area information which is indicative of an uninterrupted written initial area which extends from the start of a track pattern area intended for writing information blocks. The status information can be fixed on the record carrier. A reading device is also described, in which the positioning is dependent on the status information.
