摘要： A disk file with substantially reduced head-disk spacing and corresponding improvement in recording performance uses a disk coated with a film of conventional high viscosity lubricant, a lubricant reservoir for replenishing the lubricant on the disk over the life of the file, and a transducer carrier with feet which ski on the high viscosity liquid film. The file does not include any means for recirculating the lubricant since the lubricant spins off the disk at a relatively low rate due to its high viscosity. The lubricant reservoir contains a very small amount of lubricant and thus may be maintained inside the substantially sealed disk file. In one embodiment of the invention, the sealed disk file is essentially evacuated. The operation of the disk file in a near vacuum environment is possible because, unlike conventional disk files, air is not required to support an air-bearing head-disk interface and the high vapor pressure of the relatively high molecular weight lubricant prevents its evaporation.

摘要： A magnetic sheet control member, for use in a device for recording and reproduction using a magnetic head in sliding contact with a rotary flexible magnetic sheet, to guide the magnetic sheet to the magnetic head by a negative pressure, having upstream-side and downstream-side inclined surfaces disposed respectively at the upstream side and the downstream side with respect to the rotational direction of the magnetic sheet and inclined to become more distant from the free rotary surface plane of the magnetic sheet towards the downstream side, and stabilizing surfaces disposed respectively at the outer side and inner side with respect to the radial direction of the magnetic sheet to connect the upstream-side inclined surface and the downstream-side inclined surface, thereby obtaining a stable head contact over the entire recording area from the innermost side to the outermost side of the magnetic sheet.

摘要： A magnetic disk control member having a flat opposing surface opposing a rotating magnetic disk that defines a free rotary surface plane and provided protrudingly with a magnetic head, a protrusion for generating a negative pressure disposed at the upstream side with respect to the rotational direction of the magnetic disk, and an inclined surface disposed at an end of the opposing surface at the downstream side with respect to the rotational direction of the magnetic disk and inclined so as to gradually become closer to the free rotary surface plane towards the downstream side with respect to the rotational direction of the magnetic disk. With the magnetic disk control member, the magnetic disk is curved by the negative pressure generated at the downstream side of the protrusion to come in sliding contact with the magnetic head, and gently pushed back by the inclined surface to the free rotary surface plane side to be straightened, thereby eliminating flapping vibrations due to excessive deformation of the magnetic disk and achieving a stable and good head contact while suppressing deformation of the magnetic disk to a minimum.

摘要： Heads of a recording/reproducing apparatus are arranged so as to face two opposite recording surfaces of a disk recording medium, individually. One of the heads is fixed to a carriage, while the other is fixed to a head arm. A leaf spring is fixed to the terminal end portion of the head arm. A metal member, weldable to the leaf spring, is embedded in a fixing portion of the carriage, which is formed of synthetic resin. The leaf spring and the metal member are fixed by welding, so that two head supporting members are fixed to each other. The heads are moved on the surfaces of the disk by a head supporting mechanism, which is a combination of the two supporting members.

摘要： A data storage apparatus has a magnetic head opposed to a magnetic recording medium and movable relative to the medium so as to magnetically write or read data to or from the medium. A displacement sensor monitors a distance between the head and the medium. An actuator which supports the head is driven according to the monitored results so as to maintain constantly the distance. The actuator includes a vibrator for vibrating the head at a given frequency effective to produce air pressure against the medium. The head has a bottom face opposed to the medium and convexed outwardly toward the medium, and the medium is made of elastic material concavedly deformable in response to the air pressure.

摘要： A magnetic head supporting device includes a carriage and a head arm mounted on the carriage to be movable between a loaded position and an unloaded position. Magnetic heads are mounted on the carriage and head arm by means of gimbal springs, and face each other. Each magnetic head is urged toward a recording medium located between the heads by means of a leaf spring. When the head arm is moved to the loaded position, the heads hold the medium from both sides thereof and the gimbal springs are kept substantially undeformed by the leaf springs. When the head arm is moved to the unloaded position, the magnetic heads are prevented from moving toward the medium by stoppers provided at the carriage and head arm, respectively.

摘要： A device for coupling and aligning a rotatable disk with the motor used for rotating that disk is disclosed. The end of the motor drive shaft includes a drive spindle having a V shaped slot in its surface. This slot accepts an aligning pin which protrudes from the center of the disk. When the aligning pin is at the apex of the V slot, the disk to be rotated is concentric with the drive spindle. A drive pin, which is mounted eccentrically on the drive spindle, is in contact with a lip on the outer surface of the disk hub. Rotation of the drive spindle causes interference between the drive pin and the lip thereby imparting rotatational momentum to the disk as well as a centering force on the aligning pin.

摘要： A magnetic head assembly for a flexible magnetic disk drive unit has a magnetic recording and retrieving head for carrying out magnetic recording onto and retrieving from a metallic thin-film type flexible magnetic medium rotating about a center of the medium by coming into contact with the medium at a contact position, a first group of non-magnetic supporting pads arranged to support a plurality of positions of the flexible magnetic medium and disposed so as to surround the contact position, and a second group of non-magnetic suppressing pads in contact with a different plurality of positions of the flexible magnetic medium outward of the plurality of supporting positions so that the suppressing pads suppress any undulation of the flexible magnetic medium during rotation of the medium. The support pads and the magnetic recording and retrieving head may be formed with a recess, respectively, for trappng dust and other foreign materials, thereby preventing an accumulation of dust and other foreign materials between the head and the medium.
