摘要： An optical memory device includes a cylindrically-shaped optical information recording medium and at least one optical head disposed around the information recording medium for irradiating the information recording medium with a light spot for recording or reproduction of information. The optical head has light spot moving means incorporated therein for the irradiation position of the light spot. The recording or reproduction of information is achieved by causing the light spot moving means to perform tracking control so that the light spot follows a desired track in an area within a range of movement of the light spot by the light spot moving means (or an infromation recording zone) in a state in which the relative positional relationship between the optical head and the cylindrically-shaped information recording medium in the direction parallel to the direction of the rotation axis of the information recording medium is fixed, with the optical head being not moved. The device can be constructed so that the position of either the optical head or the cylindrically-shaped information recording medium relative to the other in the direction parallel to the direction of the rotation axis of the information recording medium is mechanically moved, thereby making it possible to cahnge the information recording zone in the range of movement of the light spot by the light spot moving means to another information recording zone.

摘要： This invention provides a method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material comprising two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. A condensation-system (liquid or/and solid) material (5) comprising the two or more isotopes is placed in a sedimentation tank (for example, 2) which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes. By virtue of sedimentation by taking advantage of this difference, isotope atoms within the condensed material interact, and, consequently, separation and enrichment of the isotopes can be realized in a higher efficiency than the case where gas is used, by conducting the separation and enrichment of the isotopes within the liquid material, using an effective material, and using a multistaged rotor system.

摘要： A fast access high capacity data storage system and method are disclosed, the data storage system including a disk-based storage system employing a plurality of storage surfaces. Selected storage surfaces have a plurality of independently controlled data access heads in data communication therewith, and circuitry is provided for allowing concurrent data transfers through the plurality of data access heads. Performance is further improved by monitoring frequently accessed data records and transferring them to a copy recording surface or recording surfaces less frequently used, and by moving a data access head of the plurality of data access heads to other recording surfaces to decrease access bottlenecks. The storage system further includes circuitry for averaging at least one of record length data, transfer timing data, access timing data and address data.
