摘要： A disk cartridge according to the present invention includes first and second disk storage portions, each of which has a space to partially store a disk with at least one data storage side. When closed up, the first and second disk storage portions enclose the disk entirely. The disk cartridge further includes a supporting base member with a disk storage portion rotation supporting portion that supports rotatably the first and second disk storage portions so as to make or cover an opening with respect to the disk. The opening is used to get the disk chucked externally and to allow a head to access the data storage side of the disk and read and/or write data from/on that side. At least a portion of the supporting base member overlaps with the first and second disk storage portions so as to prevent the first and second disk storage portions from moving perpendicularly to the disk.

摘要： The disk drive of this invention is adapted to a disk cartridge including a window allowing a head to access a disk, a shutter for opening or shutting the window, and a rotational member including a gear portion and first and second notched portions to sandwich the gear portion and interlocking with the shutter. The drive includes a transporting portion for transporting the cartridge, the read/write head, and a shutter driving mechanism, which includes a rack portion engaging with the gear portion, and first and second driving levers supported to fit into, and turn with, the first and second notched portions, respectively. The transporting portion includes a first cam structure for driving the first and second driving levers of the shutter driving mechanism such that the levers swing as the transporting portion moves. As the transporting portion moves, the first and second notched portions and the gear portion of the disk cartridge held on the transporting portion get engaged with the shutter driving mechanism, which then rotates the rotational member to open or close the shutter.

摘要： A disk drive includes base with a spindle motor, first and second rockers and first and second sliders. The spindle motor has a turntable to mount a disk. The first and second rockers rock so as to pivot about fulcrums substantially parallel to the turntable. The first rocker pulls in the disk, inserted externally, to a position where the disk and motor have their centers aligned. The second rocker unloads the disk from the position to a point where the disk is exposed partially. The first and second sliders are engaged with the first and second rockers to make them pull in and unload the disk, respectively, and reciprocate substantially parallelly to the turntable. The rockers and sliders are located under the turntable. The slider(s) support(s), raise(s) and lower(s) a side face of the base through the reciprocation.

摘要： A disk drive includes: a pair of guide walls, which is arranged in the vicinity of the holder opening of a cartridge holder to define a direction in which a disk cartridge is supposed to be inserted; a first opening/closing lever, which has a first engaging portion that engages with a portion of the disk cartridge and which rotates while the disk cartridge is being inserted or ejected; and a second opening/closing lever, which has a second engaging portion that engages with another portion of the disk cartridge and which rotates while the disk cartridge is being inserted or ejected. The first and second opening/closing levers rotate so as to leave a broader gap between the first and second engaging portions than between the guide walls when the drive gets loaded with the disk cartridge, thereby opening a window in the disk cartridge.

摘要： A guide shaft and a guide portion movably guide a lens holder for holding a collimator lens (i.e. correction lens) in an optical axis direction. A stepping motor rotates a screw shaft arranged in parallel to the optical axis direction. A nut member converts a rotating movement of the screw shaft into a rectilinear movement of the optical axis direction. An urging spring urges the lens holder against the guide shaft and the guide portion. The lens holder is driven in the optical axis direction along the guide shaft by the stepping motor, with a first contact portion and a second contact portion of the lens holder being contacted with the guide shaft, and a third contact portion of the lens holder being contacted with the guide portion by an urging force of the urging spring. The optical pickup device having the above arrangement allows for stable driving of a correction lens.
