    • A super-resolution optical head device in which a first super-resolution spot having a diameter smaller than that of a diffraction limit is formed on a recording medium by modulating beams emitted from a laser light source includes an optical system, an optical separator and a plurality of optical detectors. By the optical system, the laser beams reflected from the recording medium are converged and a second super-resolution spot is reimaged. The optical separator is constituted by a reflection-type pinhole, a diffraction-type pinhole, a refraction-type pinhole, a reflection-and-absorption type pinhole, or a set of a reflection-type pinhole and a reversed-type pinhole, which is placed at the reimaged position and optically separates the second super-resolution spot into a main beam component and a sidelobe component. The optical separator leads to the optical detectors the main beam component and the sidelobe component independently from each other. The device enables to easily obtain reproduction signals with little deterioration caused by the sidelobe component.
    • 一种超分辨率光学头装置,其中通过调制从激光光源发出的光束,在记录介质上形成直径小于衍射极限的第一超分辨率光点,包括光学系统,光学分离器和 多个光学检测器。 通过光学系统,从记录介质反射的激光束会聚并且再次成像第二超分辨率光斑。 光学分离器由反射型针孔,衍射型针孔,折射型针孔,反射型吸收型针孔或反射型针孔及反型针孔组成, 被放置在再成像位置并且将第二超分辨率光点光学地分离成主光束分量和旁瓣分量。 光学分离器将主光束分量和旁瓣分量彼此独立地导向光学检测器。 该装置能够容易地获得由旁瓣分量引起的劣化很少的再现信号。

    • A cache control method and a rotary storage device are capable at a low cost, of improving the hit rate and minimizing the processing time in the event of a miss hit. The rotary storage devices includes a plurality of disk units, an upper-level interface circuit, a cache controller, a cache memory, and a control processor. In each disk unit, the storage area of each disk is subdivided into an ordinary user data area and a secondary cache data storage area including a group of consecutive cylinders. Data which has overflowed from the cache memory is sequentially written in the secondary cache data storage area so as to be later transferred therefrom to areas of the user data area according to addresses inherent thereto when traffic of upper-level input/output processing is relatively low. In the case of a miss hit of the cache memory during a data read operation, access operations are performed first to the secondary cache data storage area and then to the user data area.
    • 能够以低成本提供高速缓存控制方法和旋转存储装置,提高命中率并最大限度地减少在命中时的处理时间。 旋转存储装置包括多个盘单元,上级接口电路,高速缓存控制器,高速缓冲存储器和控制处理器。 在每个盘单元中,每个盘的存储区域被细分成普通用户数据区和包括一组连续气缸的次高速缓存数据存储区。 从高速缓冲存储器溢出的数据被顺序地写入二次高速缓存数据存储区域中,以便随后从高级输入/输出处理的业务量相对较低地传送到用户数据区域的区域,根据其固有的地址 。 在数据读取操作期间高速缓冲存储器的未命中的情况下,首先对次级高速缓存数据存储区域进行访问操作,然后执行到用户数据区域。

    • A liquid crystal electro-optical device having gettering means therein and a method for manufacturing such a liquid crystal electro-optical device are disclosed. For example, in a liquid crystal panel disposed in the device, polyvinyl carbazole film is formed as the getting means on at least one of a pair of substrates, and the film has a function to absorb ionized impurities existing in liquid crystal disposed in the device. In virtue of the film, ionized impurities in the liquid crystal layer are decreased, and by heating the liquid crystal panel, the function of the polyvinyl carbazole film, i.e. the function to absorb ionized impurities, is enhanced. Consequently, a liquid crystal electro-optical device free from after-image which was a problem in conventional liquid crystal display devices can be obtained.
