摘要： PROBLEM TO BE SOLVED: To record an image of a near-miss appropriately.SOLUTION: A recording device in one aspect comprises an acquisition unit, a determination unit and a recording unit. The acquisition unit acquires travel information relating to traveling of vehicles including driver's vehicle and other vehicles traveling in an adjacent lane adjacent to a lane in which driver's vehicle travels. The determination unit calculates a distance between a first vehicle and a second vehicle on the basis of the travel information of the first vehicle and the travel information of the second vehicle traveling behind the first vehicle, among the other vehicles. The determination unit determines whether to record an image or not on the basis of whether or not the calculated distance between the vehicles is shorter than a threshold value. The recording unit records the image around driver's vehicle when the determination unit determines to record the image.

摘要： PURPOSE: To generate a proper tracking error signal by applying one pair of diffracted beams to a first light detection device as a first spot in a far field state before condensing light and applying them to a second light detection device as a second spot in far field state after condensing light. CONSTITUTION: Light beams emitted from a semiconductor laser 31 scan a track 37 on a magnetooptical disk 36 via a hologram element 32, a collimater lens 33, a beam splitter 34, and an objective lens 35. Optical beams applied to the element 32 are diffracted by regions 32a and 32b in the element 32 and are separated into 0-order light, ±1st-order diffraction light, and higher-order diffraction light. The 0-order light advances along a light axis 49 and is converted to parallel light by the collimater lens 33. The parallel light is applied to the lens 35 after passing through a splitter 34. Information is recorded onto the track 37 of the disk 36, is erased, and reproduced by 0-order fine beam spot formed on the magnetooptical disk 36.

摘要： PURPOSE:To make a beam shift small and to improve tracking accuracy by setting the rotational center of a galvanomirror on the virtual image face of a mobile optical part. CONSTITUTION:The galvanomirror 52 is attached to the tip side of an arm 55 pivoted by a shaft 54 on the virtual image face 38 in the case of that the mobile optical part 8 is placed to the intermediate position P0 of a moving range 9, is rotated to displace around the shaft 54 in the direction of the arrow C by the driving of an actuator 53. When the mirror is rotated and a spot 22 on an optical disk 1 is deflected by (epsilon) to the outer peripheral side, an outgoing laser beam 56 is attained to the disk 1 through an image side focus 36. Thus, a return laser beam 57 as well passes through the focus 36, coincides with the laser beam 56 and no beam shift is generated and the tracking accuracy is improved.

摘要： PURPOSE:To provide the control circuit which withstands a high plunging speed and allows high-speed accessing by determining the pulse impression time for co-earth control to a track actuator and by taking up to the acceleration of a light spot for the target track in the access direction occurring in the eccentric rotation of an optical disk into consideration. CONSTITUTION:The arrival at just before a rotating track, i.e. 1/2 before the track is detected by a plunging in position detecting circuit 20 and the plunging in speed at the point of this time is detected by using a plunging in detecting circuit 21 and the plunging in speed is detected by a projecting acceleration speed detecting circuit 25. The acceleration +alpha or -alpha predetermined in such a manner that the speed of the light spot decreases exactly to zero on the target track in accordance with the plunging in speed and plunging in acceleration detected in such a manner is applied from an acceleration/deceleration pulse generator 26 to the track actuator 14. The fine control is executed by turning off a switch 23 and turning off a switch 24 in such a manner, by which the retraction in the position 0 at the speed 0 is executed.
