A disk drive for recording data on and/or reproducing data from a disk including a base provided with a top opening and a front opening, a cassette guide member housed in the base, the cassette guide member being supported so as to be freely movable upward and downward between an upper position, where the disk is to be installed on or removed from the disk driver, and a lower position, where the disk is to be loaded at a predetermined loading position, a head unit housed in the base and having a head for recording data on and/or reproducing data from the disk, and a head arm having first and second end portions, the first end portion supporting the head, a carriage supporting the second end portion of the head arm on one end thereof, a lifting mechanism provided on the cassette guide member for elevating and lowering the head arm, the lifting mechanism comprising an upper surface of the cassette guide member, and a resilient member connected on one end thereof to the head arm and on another to the carriage, the head being movable upward and downward relative to the carriage. The head arm has a lifter portion having a contact surface, the contact surface contacting the upper surface of the cassette guide member and controlling an angle of the head arm relative to the cassette guide member when the head arm is moved to the upper position by the lifting mechanism.

Disk drive having a lifting member

A disk drive for recording data to and/or reproducing data from a disk includes a disk cassette guide and a slide plate. The disk cassette guide supports the disk during installation or removal of the disk to or from the disk drive. The slide plate has engage or upright portions which engage the disk cassette guide so as to move the disk cassette guide in response to the installation or the removal of the disk. The engage portions are disposed in concave portions formed at the side walls of the disk cassette guide. On each side of the disk drive, the outer surface of the side wall of the disk cassette guide is substantially coplanar with the outer surface of a side wall of the slide plate.

Disk drive

A disk drive for recording data to or reproducing data from a disk includes a head for writing the data into or reading the data out of the disk by sliding on the disk or gliding over the disk. An arm member holds the head which is supported by an elastic member so that the arm member can be raised or lowered. A load force is exerted on a first position of the arm member by a so as to place the head on the disk or to make the head approach the disk. An unload force is exerted on a second position of the arm member so as to separate the head from the disk. The second position is more distant from the head than the first position from the head in a longitudinal direction of the arm member.

Disk drive with low elevated head unloading mechanism

An automatic cassette loading mechanism which includes a holder which is movable in a first direction and in a second direction which is nonparallel to the first direction. The mechanism additional includes a driving motor, an insertion detecting switch, a loading completion switch, and a home position switch.

Cassette loading mechanism for a recording and/or reproducing apparatus

A clamp operating member which is bendable cooperates with a spindle to support a clamping member which cooperates to clamp a disc-shaped recording medium and to position the clamping member in a clamped position and an unclamped position. The arrangement has a restraining member engaging with the clamp operating member to bend the clamp operating member when the clamp operating member is in a position to position the clamping member in an unclamped position. The clamp operating member is bent by the restraining member when in the unclamped condition to reduce an operating space occupied by the clamp operating member.

Recording medium clamping apparatus

A hub holder which pushes the center hub of a magnetic disc to a reference surface for setting is associated with a cassette guide for guiding a magnetic disc cassette to a recording/reproducing position at which information is recorded or reproduced to or from the magnetic disc, so that the hub holder's displacement can be amplified by a required degree. An upper dust-proof door and a lower dust-proof door are swingably disposed at the cassette insertion opening of a magnetic disc unit, and they are normally so biased that they close the cassette insertion opening dust-tightly. When they are closed, one of them abuts against the other. Thus, the magnetic disc unit is compact in size and light in weight, easily clamps the center hub of the magnetic disc, and is closed in a completely dust tight manner.

Apparatus for loading a magnetic disc and for controlling the driving

This specification discloses a card processing apparatus which is constructed such that a card having information recorded thereon and a paper leaf are superposedly placed on card tray movably disposed in an opening formed within the housing of the apparatus and the following card processing is carried out by pushing the card tray into the interior of the housing: first, the card and the paper leaf are separated from each other and the card alone is transported so that first information recorded on the card is read by reader means, whereafter the card is transported back to the card tray to restore its initial position; next, information extraneously entered is compared with the first information read from the card and only when the two types of information are identical, urge means is operated to urge the superposed card and paper leaf, whereby second information recorded on the card is recorded onto the paper leaf.
