Abstract: PROBLEM TO BE SOLVED: To solve a problem with conventional disk recording and/or reproduction apparatuses, such as notebook personal computers and the like where a space (particularly, an area) occupied by a disk drive device is larger than those of the other parts provided therein, so that it is difficult to reduce the size of a notebook personal computer or the like. SOLUTION: A disk recording and/or reproduction apparatus has a turntable 18 onto which an optical disk 20 is detachably attached, a disk drive device 10 that can record and/or reproduce an information signal to/from the optical disk 20 rotated and driven by the turntable 18 while the optical disk 20 is attached to the turntable 18, and a housing 2 having a drive accommodating unit 12 in which the disk drive device is accommodated in a manner that allows the disk drive device to move. The disk drive device 10 is moved in a direction in which the disk drive device 10 protrudes from the disk accommodating unit 12 during usage, so that recording and/or reproduction is performed with respect to the optical disk while at least a portion of the optical disk 20 attached to the turntable 18 protrudes from the drive accommodating unit.

Abstract: PROBLEM TO BE SOLVED: To provide a disk driver which has highly reliable by avoiding collision with an objective lens of a pickup mechanism and other components even when a disk is inserted obliquely from a slot, and to provide an electronic apparatus having the disk driver. SOLUTION: A projecting plane 150a is formed integrally from a cover plate 150 on the cover plate 150 covering the top surface of a pickup unit 22 in the disk driver at an end part of a slot side where a disk is inserted and ejected. Further, a sheet member 151, for example, artificial leather or the like is pasted onto the projecting plane 150a. Since the providing of the projecting plane 150a makes the projecting plane 150a control an insertion angle even though the disk is inserted inclinedly to smoothly guide the disk in the direction of a disk mounting part 23, the disk is prevented from colliding with the objective lens 25a of the pickup mechanism 25 to make flaws on the disk and the objective lens.

Abstract: PROBLEM TO BE SOLVED: To raise a flying property by enhancing a CFH property, skew dependency, and line rate dependency while enhancing dust resistance.
SOLUTION: A flying head slider 1 is equipped with a leading pad 2a for assuring the stiffness in a pitch direction as a positive pressure occurrence face 2; two sets of side pads 2b and 2c for assuring the stiffness in a roll direction and disposed at a backward and right and left sides of the leading pad 2a; and a center pad 2d for controlling the surfacing property and disposed between these side pads 2b and 2c. Ingress of dust to an interface of the flying head slider and a disk is prevented by extending a step 3 one step lower than the positive pressure occurrence face 2 to forward and lateral edges at an air stream inflow side in the flying head slider 1 and stable flying property is acquired.

Abstract: PROBLEM TO BE SOLVED: To obtain a head suspension for a disk device, a suspension capable of preventing breaking of a gimbal by impact, failure of a disk by head slapping, and destruction of sliders by mutual sticking or collision. SOLUTION: A suspension 11 is provided with a limiter 17 for limiting the operating range of a load beam 14 which is formed by extending a part of a base 12 for attaching the suspension. As a result, displacement of a load beam is limited by the head suspension for a disk device; hence, a gimbal is prevented from coming into contact with the disk cartridge, even if a strong inertia force is imparted to the suspension by impact or the like, so that the gimbal is protected from destruction.
