摘要： PROBLEM TO BE SOLVED: To perform the reproduction or recording operation of the information by simultaneously loading plural optical disk recording media and using a common optical pickup head. SOLUTION: A tray simultaneously mounting a CD 10 and an MD 12 thereon is loaded and housed in the device. By transferring a block 32 of the common optical pickup head, the reproduction of the CD 10 and the recording/reproducing operation of the MD 12 are executed in order. When the MD 12 is recorded, the reproduction is executed by the integrated movement of the optical pickup head block 32 and an over-write head block 34. When the CD 10 is reproduced by moving the optical pickup head block 32 to the side of CD 10, the optical pickup head block 32 and the over-write head block 34 are separated, and the reproduction is executed by the movement of only the optical pickup head block 32 to the side of CD 10. Consequently, the operation is carried out without being disturbed by the over-write head block 34.

摘要： PROBLEM TO BE SOLVED: To optimize mass distribution of the every portion of a machine from a point of view of maintenance of attitude stabilization control and a fundamental attitude. SOLUTION: To ensure a stable starting and rising motion, an Y-axis coordinate is set at a hip joint pitch axis, an Y-axis coordinate is set at a central point between right and left hip joint roll axes, and a Z-axis coordinate is set between the hip joint roll axis and a trunk roll axis. Further, by setting the center of gravity of a portion above a neck joint roll axis to a position on the neck joint roll axis, a generating amount of a roll axis moment through neck roll movement is relieved. This constitution prevents ZMP attitude stabilization control of the whole of a machine from being influenced by neck roll movement. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To save a space, especially a space when seen from a plane. SOLUTION: This recording and/or reproducing device is provided with a recording and/or reproducing means 280 for recording and/or reproducing a signal in a recording medium 10, a carrying means 150 for carrying the recording medium, a first slider 220 moved in one direction to move the carrying means with the recording medium to a drawing-in position, and a second slider 210 moved roughly in the same direction as that of the one direction to move the recording medium carried by the carrying means to a recording and/or reproducing position corresponding to the recording/reproducing means. The first slider and the second slider are laminated on each other.

摘要： PROBLEM TO BE SOLVED: To properly drive both of an optical disk and a magneto-optical disk without enlarging a device. SOLUTION: This device is provided with a disk table for selectively loading an optical disk 100 dedicated for reproducing or a recordable magneto-optical disk 200 having an outer diameter smaller than that of the optical disk, an optical head emitting a laser light from the surface side of one of the optical disk and the magneto-optical disk and movable in the radial direction of the optical disk/magneto-optical disk, a fixed magnetic head 6 disposed in a side opposite to the optical head sandwiching the magneto-optical disk, positioned corresponding to the moving range of the optical head with respect to the magneto-optical head, and having plural cores arrayed in the moving direction of the optical head, an optical head position detecting means for detecting the moving position of the optical head with respect to the magneto-optical disk, and a driving means for applying a driving voltage to the core of the fixed magnetic head positioned oppositely to the optical head detected by the optical head position detecting means.
