摘要： A scanning device for scanning data-carrying disks. The disks include a magnetisable layer to and from which data is written and read using a magnetic transducer, such as a Giant Magneto-Resistive (GMR) transducer. Positioning of the transducer over a data track is achieved by optical tracking using a land/groove structure, and positioning of the transducer with respect to the optical tracking system by means of a reference beam transmitted through the disk.

摘要： An information carrier (10) has an information plane that has a pattern of superparamagnetic material constituting an array of storage locations (11). The presence of a specific superparamagnetic material (12R, 12G, 12B, 12Y) at the information plane represents a value of a storage location. The superparamagnetic materials have a specific response to a varying magnetic field, e.g. a known decay time. A storage unit has an interface surface (32) for cooperating with the information plane, and has coils (27) for generating the varying magnetic field. The interface surface has an array of magnetic sensor elements (24,25,26) each having a sensitive area for generating a read signal. A processing unit (33) detects said presence via the specific response by processing the read signal.
