    摘要: A track position detecting mechanism is used to detect an outermost peripheral track position of a magnetic disc for use as a reference point in making various accesses to the magnetic disc. The track position detecting mechanism has an optical detector including a light emitting element and a light receiving element, where an optical path is formed between the light emitting element and the light receiving element, and an interrupt member provided at such a position on a carriage that the interrupt member interrupts the optical path within the optical detector when a magnetic head is located at an outermost peripheral track position on the magnetic disc. The optical path substantially coincides with a plane which includes a center line of a guide shaft which guides the carriage, and the plane is parallel to a base of the carriage.

    摘要: A magnetic head carriage device which comprises a head carriage body provided on a magnetic disk drive apparatus slidably in a radial direction of a magnetic disk and in parallel to a guiding axis, an upper arm provided on the head carriage body to have an upper magnetic head on its lower surface, and a plurality of bearing members each having an annular bearing portion and a mounting arm, the annular bearing portion into which a guiding shaft is inserted along the guiding axis, the mounting arm portion extending outwardly from the annular bearing portion, the mounting arm portion of each of the bearing members being fixed to the head carriage body such that the annular bearing portions are located laterally from the head carriage body. The magnetic disk drive apparatus employing this magnetic head carriage device can be constructed to suit the demands in the field, especially one having an overall thickness smaller than that of a conventional magnetic disk drive apparatus.

    摘要: An electromagnetic relay comprises an elongated coil bobbin having an axially extending bore and carrying therearound an excitation coil, a generally U-shaped yoke with first and second yoke members, and a generally U-shaped armature with short and long legs connected by a web. The yoke and the armature are magnetically coupled together partly within the axial bore of the coil bobbin to form a magnetic circuit with the excitation coil such that the armature is movable between a set position of closing a relay contact and a reset position of opening the relay contact. The first yoke member extends into the axial bore to define at its free end a first pole end while the second yoke member extending outwardly of the excitation coil to define a second pole end. The short armature leg extends into the bore in an overlying relation with the first pole end, while the long armature leg extends outwardly of the coil in adjacent relation to the second pole end. The armature defines a bearing edge at an inner corner between the web and the short leg and is pivotable relative to the yoke with the bearing end supported on a pivot edge formed at the end of the first pole end. A hinge spring is fitted into the axial bore of the coil bobbin to urge the bearing edge of the armature against the pivot edge of the yoke at an optimum contact pressure.

    摘要: A flexible magnetic disk, rotatably housed in an apertured envelope to make up a disk cartridge, is loaded through an entrance slot in the housing of the apparatus to a preassigned position for data transfer with a pair of transducer heads on its opposite sides. Upon subsequent manipulation of a clamp know, one of the transducer heads is sprung into forced contact with the other transducer head via the magnetic disk therebetween. In order to avoid the direct contact of the two transducer heads as a result of the user's tampering with the clamp knob when the disk cartridge is not loaded in the apparatus, a head control mechanism is provided for holding the transducer heads away from each other when the disk cartridge is not loaded, even if the clamp assembly is then actuated inadvertently. The head control mechanism allows the one transducer head to travel toward the other for the establishment of data transfer contact with the magnetic disk only when the clamp knob is actuated following the insertion of the disk cartridge in the entrance slot.
