PROBLEM TO BE SOLVED: To provide a disk drive apparatus which rotates a disk-like recording medium at a constant velocity and which can print visible information such as characters and patterns by ejecting ink droplets onto a label surface of a disk-like recording medium being rotated at a constant velocity. SOLUTION: When printing visible information on the label surface of an optical disk, a control unit uses a predetermined address among a plurality of addresses as a constant velocity rotation address and performs disk constant velocity rotation processing to continuously reproduce a constant velocity rotation address by an optical pickup.

PROBLEM TO BE SOLVED: To counteract differences occurred in the print density between the inner and outer peripheries of the print region when the angular velocity of a rotated printed object and the timing for ejecting ink droplets are both constant for a print apparatus that prints visible information on a print surface of the rotated printed object by ejecting ink droplets from ejection nozzles provided on a print head onto the rotated printed object. SOLUTION: The apparatus includes a print control unit generating ink ejection data based on visible information while controlling a print head by the ink ejection data, the print control unit converts the visible information expressed by using biaxial perpendicular coordinate data, to polar coordinate data and carries out dot density correction that applies a correction weighting calculated in accordance with the number of dots per unit area for each dot in the polar coordinate data to a luminance value of each dot to generate the ink ejection data.

Abstract:
PROBLEM TO BE SOLVED: To solve the problem that in a printing device printing visible information on a printing surface of a rotated object to be printed by ejecting ink drops from an ejection nozzle provided on a printing head, printing density is different in inner and outer peripheral parts of a printing region when angular velocity of the rotated object to be printed and timing of ejection of the ink drop are constant. SOLUTION: Visible information represented by biaxial orthogonal coordinate data is transformed into polar coordinate data satisfying a relation of P R =2πP θ /(N n -N n-1 ), wherein a dot pitch of dots arranged in a radial direction and a dot pitch of dots arranged in an angle direction are defined as P R and P θ , respectively, and the number of dots of entire periphery of an n-th round from the center of the polar coordinate data is defined as N n . The polar coordinate data are binarized to form ink ejection data. Printing is performed based on the formed ink ejection data. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To reduce the size and weight of a laser block by providing a fixed semiconductor laser part having at least a semiconductor laser, an imaging optical system part moving corresponding to a laser beam emitted position, and an optical fiber for coupling the laser part to the optical system part. SOLUTION: A semiconductor laser part 31 is connected to one end of an optical fiber 72 through an optical fiber connector 71-1. The other end of the fiber 72 is connected to the focusing optical system part 30 through an optical fiber connector 71-2, and the length of the fiber 72 is formed longer than the width of a printing plate in the axial direction of a plate cylinder. Since only a laser block having the optical system may be mounted at the laser moving stage 28 of the semiconductor laser and optical system, the size and weight of the moving part can be reduced. The problem of the inertia at the time of moving is substantially eliminated by the reduction of the weight of the moving part.
