  • Patent number: 5444687
    Abstract: In a method and a device for accessing an optical disc such as a Compact Disc, a CD-ROM, a CD-I and a MD, an optical disc in which data is recorded or to be recorded at a constant linear velocity is rotated at a substantially constant number of revolution per unit time and this optical disc is accessed on the basis of a clock signal which changes its frequency in accordance with an access position (i.e., a read position or write position). Since random accessing is made in a state in which the optical disc is rotated at a substantially constant number of revolution per unit time, it is not necessary to wait in accessing until a stable revolution number is attained but the waiting time is determined only by time required for moving of the read head. This enables the waiting time to be reduced and thereby realizes accessing to the optical disc at a higher speed.

  • Patent number: 5416497
    Abstract: A video display control system displays a multicolor animation pattern on a screen of a video display unit. The video display control system is mainly constructed by a video RAM (VRAM) and a video display processor (VDP). The VRAM stores animation pattern data, display position data and at least two color data. The VDP reads these data and makes an animation pattern image displayed in at least two colors at a display position on the screen. The animation pattern image, two colors and display position are determined by the animation pattern data, two color data and display position data. In another video display control system, the VRAM stores at least two sets of animation pattern data, display position data and color data. When displaying two animation patterns, the VDP effects a logical operation on the two color data with respect to the overlapping portion of the two patterns and makes the overlapping portion displayed in a new color corresponding to the operation result.
