Optical disc device and spherical aberration error signal detection method

Provided is a disk conveying device including a conveying mechanism configured to convey a disk recording medium inside and outside a disk cartridge including a plurality of holding grooves into which both end portions of the disk recording medium positioned at opposite sides with a center hole interposed therebetween are inserted, the plurality of holding grooves being formed in a line in a thickness direction of the disk recording medium, and a discharge lever configured to press an outer circumferential surface of the disk recording medium to the disk cartridge side when the disk recording medium is conveyed by the conveying mechanism.

Disk conveying device

There is provided a disk drive apparatus including a first chassis unit that has a pickup base at which an optical pickup and a disk table have been disposed, and a first base chassis to which the pickup base has been attached, and a second chassis unit that has a second base chassis and at which a chucking pulley has been disposed. A first rectifying plate part is provided at the first base chassis. A second rectifying plate part is provided at the second base chassis.

Disk drive having chasses with rectifying plates

A disc conveying device includes a route adjuster which is pressed and turned by a disc-shaped recording medium being conveyed in a direction orthogonal to a central axis direction in a lead-in direction of being extracted and led in from a disc cartridge and an ejecting direction of being stored in the disc cartridge after being ejected; wherein a positioning groove is formed to the route adjuster, in which a peripheral portion of the disc-shaped recording medium is inserted at the time of the disc-shaped recording medium being conveyed, so as to position the disc-shaped recording medium.

Disc conveying device

A disk transportation device includes a pair of rotation arms that are rotatable respectively about a fulcrum shaft extending in the same direction as the axial direction of a center shaft of a disk-shaped recording medium in both sides thereof that pinch the transportation passage of the disk-shaped recording medium transported between a disk changer and a disk drive device; and four transportation rollers of which two at a time are rotatably supported on the pair of rotation arms respectively, wherein the four transportation rollers contact the outer peripheral surface of the disk-shaped recording medium respectively and the pair of rotation arms are rotated in opposite directions to each other in a state where one of the transportation rollers at a time is supported at the pair of the rotation arms respectively contact the outer peripheral surface of the disk-shaped recording medium.

Disk transportation device and disk storage system

A disc conveying device includes a pair of rails positioned on opposite sides across a disc-shaped recording medium transported in the lead-in direction or ejecting direction in a direction orthogonal to a center axis direction, and extending in the direction of the conveyed disc-shaped recording medium; link arms that are turnably supported to a base chassis, are turnable as to the pair of rails, and move in parallel in a direction of separating the rails from the peripheral face of the disc-shaped recording medium; conveying rollers that convey the disc-shaped recording medium by being supported by the rails, and touch the peripheral face of the disc-shaped recording medium with at least one conveying roller rotating; and an ejecting lever that is turnable as to at least one of the rails, by which turning the peripheral face of the disc-shaped recording medium is pressed, and the disc-shaped recording medium is conveyed.
