Abstract: PROBLEM TO BE SOLVED: To obtain a levitation-type floppy disk drive which prevents a disk from being damaged by an edge at a recessed part. SOLUTION: Two rails 2a, 2b protrude on a face in which a slider 1 faces a disk. When the disk is turned at high speed, the slider 1 is levitated. A head chip 6 is assembled into the rear side of one out of the rails 2a, 2b, e.g. the rail 2b. In a state that the slider 1 is levitated, a signal is recorded/-reproduced. In order to set the interval (the levitation amount) between the face of the disk and the gap of the head chip 6 to a prescribed value, slots 7a, 7b are formed nearly in central positions of the rails 2a, 2b. An angle formed by the face in which the slider 1 faces the disk and by side faces of the slots 7a, 7b is set at an obtuse angle. Thereby, it is possible to prevent the disk from being damaged by edges at the slots 7a, 7b. In addition, the depth D of the slots 7a, 7b is selected to be a value between 4 to 20 μm, and the levitation amount is made proper.

Abstract: PROBLEM TO BE SOLVED: To record/reproduce data on a standard recording density floppy disk and a high recording density floppy disk. SOLUTION: Two rails 2a and 2b are projected on the surface of a slider 1, opposite to the disk. A head chip 5 of a lower order mode for recording/ reproducing data in contact with the disk is set in the middle position of the rail 2a, while a head chip 6 of an upper order mode is set in the rear side of the rail 2b. The head chip 6 is brought into contact with the disk to record/ reproduce data. When the disk is rotated at high speed, the slider 1 is floated up. Under the floating state of the slider 1, a signal is recorded/reproduced. In order to make a space (a floating amt.) between the disk recording surface and a gap of the head chip 6 a prescribed value, slots 7a and 7b are provided in approximately the middle positions of the rails 2a and 2b. The slot 7a is formed by cutting a place between a recording and reproducing head 51 of the head chip 5 and an erasing head 52.

Abstract: PROBLEM TO BE SOLVED: To improve the coupling strength of a first member and a second member. SOLUTION: The lens unit is provided with a movable part 49 moved in an optical axis direction with respect to a lens barrel 11. The lens barrel is constituted by coupling the first member 12 and the second member 13. Pieces for fixing 17, 17, 25 and 25, respectively positioned separately in the coupling direction of the first and the second members in a state with the lens barrel constituted, are provided in the first and the second members. Fixing means 73 and 73 are loaded between the respective pieces for fixing in a state where the first and the second members are coupled with each other. The respective pieces for fixing are provided, at positions where force is applied in a direction where the fixing means are compressed by the respective pieces for fixing, when a force applied to the first and the second members, in a direction where the coupling of the first and the second members is released with the first and the second members being coupled to each other.
