    Abstract: A data transfer apparatus employs a pair of magnetic transducer heads for contact with the opposite faces of a magnetic disk for data transfer. The magnetic disk is rotatably housed in a relatively rigid envelope to make up an interchangeable disk cartridge, with the envelope having a shutter openable to expose parts of the opposite faces of the magnetic disk for data transfer contact with the transducer heads. The apparatus has a cartridge cradle movable between a first position where the disk cartridge is loaded on and unloaded from the same, and a second position where the loaded disk cartridge engages with a disk drive mechanism to be driven thereby. The cartridge cradle is dually locked against accidental travel from the first to the second position, in order to prevent the collision of the pair of transducer heads with each other. As the second locking mechanism, in addition to the first which is normally employed for latching the cartridge cradle in the first position, a lever for opening the shutter of the disk cartridge is adapted to positively lock the cradle in the first position even if the first locking mechanism is tripped accidentally.

    Abstract: An apparatus for recording flexible magnetic disks contained in envelopes comprises a mandrel engageable with a central zone of the disk to rotate the disk within the envelope, and a carriage 41 which is movable radially relative to the disk and on which there is mounted a pair of magnetic heads which oppose each other and make contact with the magnetisable surfaces of the disk. The carriage 41 is moved on guides 48 by a stepping motor shaft 44 by way of a pair of flexible strips 50, 51 which are partly wound about a hub 59 on the shaft 44. The ends of the strips are retained by longitudinal pins 70 loosely fitted into an eccentric bore in the hub 59 without the aid of screws. Pegs 71 on the pins 70 pass through holes in the ends of the strips 50 and 51 and are arrested against the motor shaft 44. A presser pad, which presses the envelope containing the disk against a reference surface of the apparatus, is lowered by an electromagnet which also causes the upper head to lower. A lost-motion form of coupling enables the pad and upper head to carry out independently adjustable travel strokes, so minimising any recoil.

    Abstract: The present invention relates to a disk drive seek control system which is capable of rapidly moving a transducer (18) from an initial position to a target position above a data storage medium (12). The system applies control to an actuator motor means (20) based on projected transducer velocity at a future servo sample time. This allows the system to significantly reduce transducer velocity profile. In addition, the system utilizes dynamically adapted feed forward deceleration current during a deceleration portion of the seek cycle to further reduce velocity errors during the seek cycle, the system significantly reduces the length of time required for settling the transducer (18) on the track (14) of the disk (12) after the seek cycle has ended.

    Abstract: A single mechanism is used to launch and retract the read-write heads from the medium of a disk drive. The mechanism includes a retraction lever (91), a retraction lever lock (118), a mechanical biasing member (76), a disk (37), and a voice coil motor (16). During launch of the read-write heads, the mechanical biasing member balances the emf generated by the voice coil motor. After launch, the voice coil motor is used to rotate a retraction lever and increase the potential energy in the mechanical biasing member. The retraction lever lock then is used to store this built-up potential energy. If the drive later experiences a loss of power, the mechanism automatically retracts the read-write heads from the media. During retraction of the read-write heads, the stored mechanical energy is applied to the retraction lever, which then automatically retracts the read-write heads.

    Abstract: A passive non-contact magnetic latch (60) for latching read-write heads of a disk drive over a landing area of the disk is disclosed. The magnetic latch forms a magnetic circuit for capturing a latch tab (48) within an air gap (61). Magnetic flux lines traverse the latch tab in a direction substantially perpendicular to a direction of movement of the latch tab.
