摘要： A magneto-optic data recording system and actuator therefor comprises a permanent magnet mounted adjacent to a magneto-optic disk medium. The permanent magnet is rotatable about its longitudinal axis to change the polarity of the magnetic field which supplied to the medium. Rotation of the magnet is achieved by activation of electromagnet actuators located laterally adjacent to the permanent magnet. Rotation of the magnet through 180 o is preferably achieved within less than 1 period of revolution of the disk, preferably less than 1/2 the period of revolution of the disk.

摘要： A magneto-optic data recording system is provided in which the magnetic field production apparatus is disposed on the same side of the disk as the optics, to provide reduced height requirements. Preferably, two magnets are disposed on either side of the optics to provide a resultant magnetic field which is perpendicular to the plane of the disk. By using permanent magnets which are rotatable in opposite directions, a variable field strength is achieved. Preferably, two permanent magnets extending across the recording medium are related by gears to produce equal and opposite rotation which is mechanically independent of movement of other portions of the apparatus.

摘要： An apparatus reads and/or records information on a disc 3 by means of a light beam 20, which disc rotates about an axis of rotation 2 and is driven by a drive spindle 31 which is journalled in a spindle support 30, an objective 1 being moved along two parallel guides 9 by means of a slide 6 in a radial di- ection relative to the axis of rotation 2. All parts of an opto-electronic system for producing the light beam and for effect- ng a conversion between optical and electrical modulation may be arranged on the slide but may alternatively form part of a stationarily arranged opto-electronic system 33. At least the spindle support 30 or the stationarily arranged opto-electronic system 33 is supported by the guides 9, for example by means of supports 39 and 40 which are formed with locating surfaces which cooperate with the guides 9A and 9B.

摘要： The invention relates to a radiation-beam manipulator (1) comprising a first part (3) and a second part (7) with a mirror surface (21) which is pivotable relative to the first part about at least one pivot axis (29,31). The manipulator further comprises a system of actuators (35,37,39,41) for pivoting the second part about said pivot axis, said system of actuators comprising a system of electric coils (43,45,47,49) and a system of permanent magnets (51,53,55,57) co-operating with the system of coils. In accordance with the invention, the second part is pivotably journaled relative to the first part by means of a bearing (5,9) comprising a thrust surface (15) and a further bearing part (25) co-operating with said thrust surface, which further bearing part is pretensioned relative to the thrust surface by means of a system of magnetizable elements (59,61,63,65) exerting a magnetic pretension force upon the permanent magnets of the system of actuators parallel to a support axis (67) of the bearing. The magnetizable elements also exert a magnetic torque (M z ) upon said permanent magnets about said support axis.
The manipulator is used in a laser-processing device (69) for selectively deflecting a laser beam (93) to a piece of work (75) to be processed.
