    摘要: An optical disc apparatus can make the focus of an information light beam converged by an objective lens agree with a target track of a target mark layer of an optical disc by appropriately predefining the distance between the focus of a servo light beam and that of the information light beam with regard to the direction of the thickness and a radial direction of the optical disc by means of the optical pickup of the apparatus and then operating for focus control and tracking control of the objective lens so as to make focus of the servo light beam converged by the objective lens agree with a reference track of a reference mark layer.

    摘要: An optical disc apparatus can highly accurately record a hologram representing information on or reproduce such a hologram from an optical disc. When recording information on an optical disc 100, the optical disc apparatus controls the position of an objective lens OL1 according to the outcome of detection of a red reflected light beam Lr2 so as to make the focus Fr thereof follow a target track and it also makes the focus Fb1 of a blue light beam Lb1 agree with a target mark position by the objective lens OL1 and also the focus Fb2 agree with the target mark position by controlling the position of another objective lens OL2 according to the outcome of detection of the blue light beam Lb1 by way of the objective lenses OL1 and OL2 so as to make the focus Fb1 of the blue light beam Lb1 and the focus Fb2 of the blue light beam Lb2 agree with the target mark position and the blue light beam Lb1 and the blue light beam Lb2 interfere with each other. Thus, as a result, the optical disc apparatus can record a recording mark RM at the target mark position.

    摘要: A recording apparatus for recording data on a recording medium having at least one recording layer, includes a loading unit and a recorder unit. On the loading unit, the recording medium is capable of being loaded. The recorder unit is configured to cause the at least one recording layer a physical change to collectively record a plurality of pieces of data on the at least one recording layer of the recording medium loaded on the loading unit, in a thickness direction of the at least one recording layer, such that the physical change of the at least one recording layer is capable of being detected at one time when the recording medium is reproduced.
