摘要： The present invention provides an optical disk control device that can perform focus pulling in a short time for a target information surface of an optical disk having a plurality of information surfaces. An objective lens (23) is moved toward an optical disk (1) having a plurality of information surfaces (1A, 1B) by the output signal of a driving signal generating circuit (42B), passage of an initial focused focal position is detected by a focal point passage detecting circuit (44), and when the objective lens moves past that position only a predetermined amount closer to the optical disk, an n-rotation delay circuit (70) outputs a reversal instruction f. After changing directions and moving the objective lens away from the optical disk, a focus pulling-in circuit (32B) switches a signal “a” that is output to an actuator driving circuit (21) from the output signal of the driving signal generating circuit to the output signal of the control circuit, activates a control circuit and performs focus pulling-in.

摘要： To find out a crystalline material for a high speed scintillator in place of BaF2 and the like, and a method for producing the material at a low cost. A single crystal of (Zn1−xMx)O1+x (M: Al, Ga, In, Y, Sc, La, Gd, Lu) (x=0 to 0.0500), (Zn1−xM′x)O1+2x(M′: Si, Ge, Sn, Pb)(x=0 to 0.0250) or (Zn1−xCdx)O (x=0 to 0.0500) is used as a scintillator. Defects of a ZnO single crystal can be reduced by using a platinum inner cylinder in order for a solution not to directly contact with an autoclave, for reducing impurities in the ZnO single crystal and precluding impurities interfering with scintillation, and by using LiOH and KOH as a mineralizer. ZnO can be doped with Al2O3, Ga2O3, In2O3, Si, Cd or the like by adding those materials to a starting material for the hydrothermal synthesis. The doping amounts can be controlled by changing charging amounts thereof. The doping of those elements inhibits the emission of visible lights, which results in the efficient transformation of the excitation energy to the luminescence from a free exciton.

摘要： To provide an apparatus that can prevent an objective lens from colliding against a member of a disk drive, can get disk loading/unloading operations done quickly and can establish a focus controlled state swiftly. An information processing apparatus includes: a converging section for converging light; a shifting section for shifting the focus of the light by moving the converging section perpendicularly to an information storage layer of a storage medium responsive to a drive signal; a position control section for generating a position control signal to move the converging section at variable velocities; a focus control section for generating a focus control signal based on a light amount signal representing reflected light such that the focus is located in a focus controllable range; a switching section for selectively outputting the position control or focus control signal; and a driving section for outputting a drive signal responsive to the output signal. The switching section outputs the position control signal to shift the focus to the focus controllable range and the focus control signal.
