    摘要: 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. Reading instructions with addresses outside the initial area can be rejected or translated via an address translation table into addresses in the initial area.

    摘要: Apparatus for scanning a rotating information carrier having mutually substantially parallel tracks for the recording of information. The apparatus includes a transducer for scanning the information carrier and for generating a position signal which indicates a position of a scanning point scanned by the transducer. The apparatus further includes means for rotating the information carrier about an axis and means for moving the scanning point in a radial direction with respect to the axis. The apparatus has a scanning mode in which the scanning point jumps both from one track to another in a first radial direction and from one track to another in an opposite second direction during reading or writing of a file.
