IPC: G01Q60/00

Abstract: A method for recording, reading and erasing data bits in a data storage device is described. Using extended scanning tunnelling microscopy (STM) techniques, a tunnelling electron current by resistive heating selectively melts discrete areas of a state-transformable film; then heat is dissipated rapidly, writing data bits by changing the film in the areas from a first state to a second state wherein an electronic property, such as conductance, work function or band gap, in the areas is changed. Again, using extended STM techniques, the effect of this changed electronic property of the film on the tunnelling current is measured for reading the written data bits. Minimising the effect of blemishes on the material is effected, during operation in STM constant current mode by measuring dI/dV or dI/ds, and during operation in STM variable current (constant gap) mode by measuring (dI/dV)/I or (dI/ds)/I. Also, by using extended STM techniques, data bits can be selectively erased by resistance heating the film to a temperature higher than the crystallisation temperature for a sufficient period of time, restoring selected discrete areas to the first state and each affected electronic property substantially to its original condition.

Abstract: Fine tracking and focusing actuators are removed from the optical head and implemented in a stationary beam control unit (30). Preferably, an optical relay in the control unit includes an optical component movable axially for remote focusing and perpendicularly for remote fine tracking. Only a folding mirror (20) and objective lens (18) remain on the moving head. Removing the fine tracking and focusing mechanisms from the head lowers the mass of the head and removes associated compliant components thus enabling higher accelerations, shorter settling times and overall faster access times.

Abstract: In an optical unit (2) incorporated in a laser beam printer, a light beam generated by a laser diode (12) is converted by a group of conversion lenses (10) into a light beam having a predetermined-size cross section. The light beam is directed toward a photosensitive body (90) by a scanner unit (50), so as to scan the photosen­sitive body (90). A group of focusing lenses (70) allow the rotating angle of the mirrors of the scanner unit (50) to correspond to a desirable point on the surface of the photosensitive body. In other words, the rotat­ing angle is made to correspond to the distance between the optical axis center determined with respect to a main scanning direction and a point to which the light beam is irradiated for scanning. The conversion lenses (10) include at least one aspheric glass lens (14), and at least two plastic lenses (16, 18) which are formed of the same material. The focusing lenses (70) include at least one plastic lens (72) which is formed of the same material as the plastic lenses (16, 18) included in the converting lenses. With respect to these lenses (14, 16, 18, 72), optical correction is made in order to eliminate adverse effects which may be caused by temperature- and/or moisture-dependent focal length variation and by temperature- and/or moisture-dependent deformation of the plastic lenses.
