Abstract: @ A magnetic tape recording and reproducing apparatus uses a cassette having a pressure roller near one corner with an aperture in one adjacent edge for a drive roller to engage the tape and an aperture in the other adjacent edge for the tape to engage a transducing head. The drive roller and head are fixed in position and a spring presses the cassette towards the drive roller, the pressure on the pressure roller also serving to retain the cassette and locate it against fixed stops. The head has projections for aligning the tape and determining the position of the cassette. The head position is referenced to the casing by standing on a surface of the casing and being held in place by resilient arms secured to the casing. The head is connected to a read-write circuit using a push-pull amplifier powered by two current sources. Any one of a plurality of such apparatus can be selected using a chain of D-type flip-flops (one per apparatus) and applying a number of clock pulses corresponding the apparatus to be selected.

Abstract: A magnetic transducer head (10) comprises a write module (14), with a write chip (18) and write closure (20), and a read module (16), with a read chip (30) and a read closure (28). The chips and closures form write transducing and read transducing gap lines (22) and (32). The head (10) has an operative face (44) which interfaces with a movable magnetic tape (12). Slots (24) and (38) are formed in the leading and trailing faces (26) and (40) of the face (44) and slots (34) are formed in the operative face (44) on the read closure (28). A recess (41) and tube (42) in the read closure (28) provide a passage at the approximate centre of the head (10) leading to a connector tube (50). The passage (50) leads to normally open valve (48) and normally closed valve (46). The other side of valve (48) is open to atmosphere and that of valve (46) to a fluid pressure pump (54). By operation of the valves (46) and (48), fluid under pressure is introduced to the operative face of a magnetic head to lift the magnetic tape into a tent-like structure (56) out of contact with the transducers on the gap lines when the tape is stationary or about to be stopped. The fluid pressure tents the tape with the pressure such that the tape forms a restricted exhaust with the head at the edges of the tent-like structure. The valves are operated to connect the operative face to atmospheric pressure to permit the tape tension to quickly pull the tape back into operative relation with the transducers by assisting the slots in dissipating the fluid pressure.

Abstract: A head suspension (10) has an integrated two-layer trace conductor array (16) for supporting and electrically interconnecting a dual element read/write head (20) to electronic circuitry in a disk drive (30) while providing reduced susceptibility to electromagnetic interference and stray signal pickup. Two sets of trace segments (60, 62) on two layers (25, 27) are formed in a crossing, "twisted wire" pattern, and are connected into a two conductor signal path by vias (70) extending between the two layers. A laterally and elevationally transposed multi-conductor trace array (16A) is also described.

Abstract: A transducer (35) suspension (30) for a drive system has a beam (33) which is bendable in a vertical direction for holding the transducer adjacent to the media, but is torsionally stiff for wuicker access times and reduced noise and errors. This inherently contradictory performance occurs by joining a laterally elongated brace (53) which is torsionally stiff about its elongated dimension across a pair of laterally disposed strips (48, 50) to cause the strips to flex in unison, allowing bending but reducing torsional motion in the suspension about an axis which is substantially perpendicular to the torsionally stiff axis of the brace. The torsionally stiff brace may take the form of a tube having a rectangular (53), triangular (95) or circular (71, 72) cross section, and may be formed of material cut from the suspension to define the hinge strips. The brace may have reduced longitudinal dimensions at the connections to the strips to further filter torsional versus bending vibrations. A plurality of braces (166) joined to hinge portions (160, 161) may also occur in a single suspension for increased effect.

Abstract: A head/gimbal assembly (HGA) of a suspension system for a disk drive includes a uniquely configured flexure tongue which allows for parallel positioning of a slider air bearing surface (ABS) during merge and a limitation of pitch of the slider during non-merge. A cantilevered end of the flexure tongue is provided with a finger extension which can be employed for merge operations and a remainder cantilevered end portion adjacent a base of the finger can be employed for limiting pitch of the slider. When a merge comb engages multiple flexure fingers of multiple suspensions in a head stack assembly the air bearing surfaces of the sliders are positioned parallel with respect to one another. This allows maximum disk stack density when a head stack assembly is merged with a head stack assembly. The flexure finger allows various arrangements to be employed for implementing a merge. The present invention also cooperates with a prior art roll limiter so that during merge a three point fixation normalizes a slider at zero pitch.

Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.

Abstract: In a support device for electromagnetic transducer heads (24) of a magnetic disk memory with a pile of magnetic disks (12, 13), the transducer heads (24), which can be adjusted radially with respect to the axis of the disks, are attached by means of an arm-like suspension (18, 20) to a support (10) which can be adjusted with respect to the magnetic disks in the direction of the chord. The transducer heads (24) associated with the mutually facing surfaces of two adjacent magnetic disks (12, 13) are axially superimposed. The suspensions (18, 20), each of which carries two superimposed transducer heads (24), are mutually offset by an angle, measured in the plane of the disks, such that their points of attachment to the support (10) are not axially superimposed.

Abstract: A transducer element assembly comprises a transducer element (2l,) having a scanning surface for scanning a recording surface of a recording medium, a cantilever (ll,) having the transducer element provided on a free tip end thereof and having a pair of holes (l4, l5;) provided on a root end thereof, a support part (l2,) having a pair of generally conical pivots (l7, l8;), and a magnetic coupling mechanism (l3, l9; l3,) provided on the cantilever (ll) and on the support part (l2) for magnetically coupling the two by a magnetic attraction or repulsion. The cantilever (ll) is detachably mounted on the support part (l2) and is user replaceable. When the cantilever (ll) is mounted on the support part (l2), the pivots (l7, l8) engage the corresponding holes (l4, l5) and the cantilever (ll) is rotatable about the root end thereof in a direction approximately perpendicular to the scanning surface of the transducer element. The magnetic attraction or repulsion generated by the magnetic coupling mechanism acts with a predetermined magnitude in a predetermined direction so that the transducer element (ll) makes contact with the recording surfac e of the recording medium with a predetermined contact pressure.
