Disk loading device

Abstract: PROBLEM TO BE SOLVED: To surely prevent the errors in the insertion of a small diameter disk due to carelessness or the like by providing a pair of independent disk insertion detecting means, operated together with a prescribed size disk when it is inserted, operating a disk loading device in linkage with the detecting means and controlling the carrier enable/disable state of a disk carrier route. SOLUTION: One ends 5A and 6A of a pair of disk check levers 5 and 6, which are arranged so as to be freely rotatable with fulcrums C and D as a center, are positioned in the lower part of the other ends of roller rods 3 and 4, and the other ends 5B and 6B are formed to extend in the center part direction of a disk 9. The size of a diameter in the disk to be inserted from the side of a front panel 10 is discriminated through lever operations by the engagement of the roller rod 3 with the disk check lever 5 and the engagement of the roller rod 4 with the disk check lever 6, and also insertion of wrong size disk is prevented.

Disk sensor power system for sampling output signal of disk sensor at predetermined moments related to power saving state

Abstract: A flexible magnetic disk drive with a built-in USB interface is disclosed. A disk sensor produces an output that, in the event of a change from one disk to another during a SUSPEND state of a SUSPEND/RESUME signal, remains indicative of disk absence from the moment said one disk was unloaded to, at the earliest, the moment the SUSPEND/RESUME signal subsequently gains a RESUME state, for power-saving purposes. In order to enable the computer to know the occurrence of the disk change immediately upon resumption of disk drive operation, the disk sensor output is sampled approximately at the beginning and end of each SUSPEND state, and immediately after the beginning of each RESUME state, of the SUSPEND/RESUME signal. Six different possible histories of disk loading and unloading past each SUSPEND state are ascertainable from every three disk sensor output samples. Each such renewable history datum is stored on a memory in the interface, for delivery to the computer on demand.

Disk loading apparatus with independent detection devices

Abstract: Provided in the vicinity of both sides of a disk loading slot, are rods which rotate when contacted by a disk that is loaded, and disk check levers which are in contact with the rods and rotate by a principle of a lever. With such a disk loading apparatus, when loading a disk into a reproduction apparatus, incorrect loading of a disk due to a difference in disk sizes is prevented.

Disk loading mechanism for disk device

Abstract: PROBLEM TO BE SOLVED: To reduce the cost of production and a thickness by feeding a disk by deforming a disk feed roller which is put with a rubber tube of an equal thickness to a columnar shaft in such a manner that the part in contact with a disk is recessed. SOLUTION: A shaft 2 has a fine columnar shape and the rubber tube 3 of the equal thickness is put on this shaft, by which the disk feed roller 1 is formed. The shaft 2 is freely rotatably supported on a roller holding chassis 5 and is rotated by a rotary drive mechanism. A disk guide 4 is fixed to face the disk feed roller 1 and the disk 6 inserted between the disk feed roller 1 and the disk guide 4 is held between the disk feed roller 1 and the disk guide 4 by the elastic force of the disk feed roller 1 and is sent by the rotary frictional force of the disk feed roller 1. When the disk feed roller 1 holds the disk, the shaft 2 is elastically deformed and the disk feed roller 1 is brought into contact with only the periphery of the disk and, therefore, the disk is kept free from damage.

Disk recording and/or reproducing device, disk loading mechanism, and disk eject mechanism

Abstract: A disk recording and/or reproducing device capable of recording data onto a disk and/or reproducing data recorded on the disk, includes a disk mounting portion for mounting the disk; a chucking portion for chucking the disk in cooperation with the disk mounting portion, the chucking portion having a disk engaging portion for engaging the disk at the start of disk loading; and a slider for supporting the chucking portion and moving the chucking portion in a radial direction of the disk between a chucking position where the disk is allowed to be chucked and a loading position where the disk loading is allowed to be started. With this arrangement, the device can be reduced in thickness.

Magnetic head slider and magnetic disk loading the same

Abstract: PROBLEM TO BE SOLVED: To provide a slider which does not damage a disk with the front edge thereof even during CSS or when a magnetic slider in the floating condition is in contact with a rotating magnetic disk and also results in drop of floating due to reduction of air pressure. SOLUTION: A floating pad 10 of a magnetic head slider 11 is formed of a stepped surface 12 having a small stepped area and a flat surface 13 and a very small projected area is formed at the stepped surface 12. Height of projected area is higher than or identical to the height of stepped area. Because of a very small projected area, the slider does not easily rotate with inclination to the front side and the front edge of stepped surface does not damage the disk surface. Moreover, variation of floating amount can be reduced by a negative pressure generated in the backward direction of the very small projected area. Thereby, highly reliable large capacity magnetic disk recording apparatus can be provided.

Disk loading and clamping device

Abstract: PROBLEM TO BE SOLVED: To provide a disk loading and clamping device which realizes high- speed disk change operation in continuous reproduction, is capable of making a contribution to the simplification of the constitution over the entire part of the device and is high in operation reliability by decreasing the kinds of necessary state detection. SOLUTION: A large-diameter gear 8 rotates in two directions within a preset rotating angle. The large-diameter gear 8 first turns a loading arm 10 by means of a connecting pin 9 and a cam hole 10a in clockwise rotation shown in Figure and slidingly actuates a holder take-out pawl 11 to move a disk holder 3 within a magazine M up onto a turntable 18. By the subsequent rotation in the same direction, the large-diameter gear 8 slidingly actuates a first clamping plate 12 and slidingly actuates second and third clamping plates 13 by means of a cam hole 8a and a connecting pin 12a to rotate a drive chassis 15 up to a clamping position, thereby fixing the disk D to a reproduction position.

Disk reproducing device

Abstract: PROBLEM TO BE SOLVED: To rapidly stop the rotation of a disk at the time of ejecting the disk by braking the rotation of a disk driving device only in the period when a disk carrier is moved to the disk loading/unloading position from the disk reproducing position. SOLUTION: A driving part 5 is controlled by a control circuit so as to brake the rotation of the turntable 2, but the time for 2-3 seconds are required till the disk 1 is completely stopped. Since the disk carrier 6 is instantaneously stopped by the force of a spring, a rotary body of the disk driving device is abutted on an abutting part 10 while keeping the rotating state. The abutting part 10 is stacked with the rotary body of the disk driving device in the radial direction of the rotary body of the disk driving device, and this stacked state is absorbed by the elastic force of the abutting part 10 and the swinging movement of a swing contact means 8 between the driving part 5 and disk carrier 6. By the friction between the rotary body of the disk driving device and the abutting part 10 generated by the repulsion at this time, the rotation of the rotary body is braked and stopped, then the rotation of the disk 1 inserted onto the turntable 2 is stopped.

In this case, when the information recording disk D loaded on the turntable 2410 is taken out, a floating device 26 is provided to cause the floatation of the turntable 2410 from a rotational surface being driven toward the opening portion of the information recording disk loading recessed portion 22.

Recording medium transfer device

Abstract: PROBLEM TO BE SOLVED: To enable a nimble manipulation by providing the device with a drive mechanism for bringing a pair of recording medium transfer means to each other or parting these means from each other and detecting that the spacing between a pair of the recording medium transfer means is widened by the insertion of a recording medium. SOLUTION: As the disk 101 is inserted into the disk reproducing device 1, a detecting switch 49 goes on and the disk drive mechanism 40 and a guide member 50 are controlled to be moved in a direction parting from each other by the drive force of the slide plate drive mechanism. The spacing between the disk drive mechanism 40 and the guide member 50 is controlled to be opened by the drive force of the slide plate drive control mechanism cooperatively with the insertion of the disk into the disk reproducing device 1 and, therefore, the disk loading is made possible with light insertion force. Further, when the disk 101 is completely inserted between the disk drive mechanism 40 and the guide member 50, the detecting switch is turned on by a projecting part a microcomputer recognizes the insertion.
