    摘要： A magnetic head suitable for use in a magneto-optical apparatus. The magnetic head has a flat electromagnetic coil (1) with a central opening (3). The coil has parallel coil layers (5a, 5b), each of the coil layers having a turn (5A, 5B) arranged around the central opening. At least one of the coil layers has turns of which the turns closer to the central opening have smaller widths (w) than the turns further away from the central opening. At least one of the coil layers has an outermost turn (5Bo) situated closer to the central opening than the outermost turn (5Ao) of one of the other coil layers. The defined coil structure has a limited capacitance while the power dissipation is also limited.

    摘要： A simple method of manufacturing a magnetic head having a head face and including a planar magnetic coil (7) which extends parallel to the head face. According to the method, the magnetic coil is formed at a first side of a first substrate (1). Thereafter, the first substrate provided with the magnetic coil is adhered with its first side to a side of a second substrate, whereafter material of the first substrate is removed from a second side of the first substrate (9), the second side being turned away from the first side, in order to form the head face, in such a manner that the magnetic coil is situated near to the head face.

    摘要： An apparatus for scanning a track on a record carrier has a head (41) for providing a beam of radiation and generating at least one sensor signal. The device has a focusing unit for controlling a focusing element to maintain an in-focus position for generating a focused spot on the track. The sensor signal is converted into a displacement signal by a multitude of piecewise converters (42, 43, 44), each converter converting a range of the sensor signal values into a position signal, and selection means (46) for selecting one of the position signals as the displacement signal based on an estimated displacement.

    摘要： In the invention, e-book information is distributed on un-cartridged small media that can be made cheaply enough for use in free distribution of information. The e-book information is encoded and stored on a read-only optical disc that is 2 to 4 cm in diameter and 0.6 to 1.2 mm thick, the information being encoded with sufficient redundancy and sufficient tolerance for missing information that the disc can be conveniently handled and pocketed without losing reliability of information access. The disc has a lead-in area that is prior to all the e-book information and that contains a disc navigation area, and a lead-out area that follows all the e-book information. The disc may include multiple partitions, each partition containing sufficient access information for independent access of the e-book information within the partition without accessing any other partition. Alternatively, the disc may include multiple slots for files and that are equally spaced. For example, to provide data redundancy, at least some of the partitions are duplicate partitions that contain all the same data as another duplicate partition, and the disc navigation area contains partition descriptors that indicate all the partitions and the areas allocated to each of the partitions, and the disc also includes duplicates of the partition descriptors, the duplicate partition descriptors being stored in the lead-in area or in the lead-out area to provide redundancy of navigation information.

    摘要： A Method of Manufacturing an Integrated Magneto-Optical Element for use in a Digital Magneto-Optical Signal write/Read Head and an Integrated Magneto-Optical Element Manufactured According to the Method A method of manufacturing an integrated magneto-optical element for use in a digital magneto-optical signal read/write head, in which the manufacturing techniques of thin film coils are combined with lens-making techniques to realise a high performance, reliable and cost-effective lens-MFM coil combination for use in a slider having an air bearing surface for “flying” just above a surface of a storage medium (102) during operation.
