    Abstract: PROBLEM TO BE SOLVED: To realize recording and reproduction using a near-field light to a plurality of recording layers without performing complicated optical adjustment of a near-field optical system. SOLUTION: When a near-field light is radiated to an optical recording medium 200 having a plurality of recording layers to perform recording and reproduction, an envelope of a tracking error signal when a focal distance is changed is detected at a control section 28 and a focus control signal Sf is generated using a position where a signal amplitude becomes a maximum as a reference. By driving an aberration correction mechanism 11 and optical lenses 12 and 13 of an optical adjustment mechanism 10 based on the focus control signal Sf, favorable near-field recording and reproduction can be realized by performing focus control to the plurality of recording layers without performing complicated optical adjustment.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical disk driving apparatus in which a condensing element can appropriately be prevented from colliding with a disk, and to provide an optical disk apparatus, on which the drive apparatus is mounted, and its driving method. SOLUTION: A voltage V (V) corresponding to near field detection level 8 is held by a sample-and-hold circuit, held voltage is released once. Since voltage in which held voltage is the maximum is applied to three axis actuator, SIL approaches to a near field from distance (far field) being not near field, when it enters into the near field, speed of SIL becomes almost zero. Since gap servo is started from this zero state of speed while targeting on a gap servo target value 7, vibration caused by initial speed of SIL is prevented, overshoot can be prevented.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical disk apparatus wherein collision of a head with a disk can be reliably prevented while the time until the head is controlled so as to be moved to a target position in a near field region is shortened as much as possible and to provide its control method. SOLUTION: The optical head is approached to the disk at a distance where light from the optical head is condensed on the optical disk as near field light by approaching voltage 14 outputted by an approaching speed generation part 23, the optical head is nearly stopped there and then servo voltage 27 is outputted so that the distance between the optical head and the disk is made to be fixed. Thereby, initial speed in the state in which the optical head is at a distance of a near field can be made nearly zero and disturbance due to the initial speed can be prevented.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical disk apparatus capable of preventing illegal copy of data recorded in an optical disk and to provide its reproducing method. SOLUTION: Identification information of an IC chip 17 is received by a receiving device 18 and if the optical disk 35 is determined as an illegal copy product by an identification information collating device 19, the identification results in NG. If the identification results in NG, a control signal for controlling the shutter plate 16 so as to be shut is transmitted to a shutter driving mechanism 14. Thereby, the shutter plate 16 is shut and a laser beam of an optical means 30 is physically interrupted. Thereby, reproduction of data can not be performed and, as a result, illegal copy of the data is suppressed. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide an electronic equipment and system which can inform a user of the residual quantity of a battery without using an exclusive display element and superimposed display and without impairing the visibility of a display image even if any display system is used. SOLUTION: The electronic equipment generating an image by using polygons is constituted in such a manner that the number of the polygons of an object constituting the image is changed according to the residual quantity of the battery. As a result, the user is able to visually recognize the residual quantity of the battery by the increase and decrease of the number of the polygons of the object. Also, the equipment is so constituted as to decrease the number of clock frequencies and operating voltage of a CPU 107 as well cooperatively with the change in the number of the polygons when the residual quantity of the battery decreases and the number of the polygons decreases and therefore the number of the clock frequencies and the operating voltage corresponding to the decreased residual quantity of the battery and number of the polygons can be set and the voltage consumption can be suppressed and a power-saving effect can be obtained.

    Abstract: PROBLEM TO BE SOLVED: To effectively remove dust on an optical disk when the recording or the reproducing of an optical disk is performed by using a near-field light. SOLUTION: The optical disk is turned at an arbitrary speed before a gap control action or the like is taken place after the optical disk is set on a turn table in a main body 1. Thus, dust stuck on the optical disk is blown off to the outer peripheral side, the signal recording face of the optical disk is cleaned up. Next, the optical disk is once stopped and the gap control is performed to keep the clearance (gap) between an optical head and the optical disk in a distance with which a near-field light is generated. Then, the normal operation of the gap control is confirmed, the optical disk is turned when the gap control is normally operating, and the recording or reproducing operation of the signal with the near-field light is begun.
