    摘要： Head load pressure generation means 36 is provided that flexibly supports an upper read/write head 25, via a leaf spring 27 attached to a main body 22, that moves forward and backward along the tracks on a magnetic data recording medium 3, and that adjusts the head load pressure applied to the upper read/write head 25 in accordance with whether a high-density or a low-density magnetic data recording medium is employed. Using this means, the head load pressure and the revolutions of a chucking motor are adjusted in accordance with whether a high-density or a low-density magnetic data recording medium is employed.

    摘要： In a floppy disk drive for writing/reading information to/from a floppy disk having a magnetic recording medium of a high memory capacity, a bottom plate of a driver casing defining a floppy disk containing space has a plurality of exhaust ports for expelling dust outside therethrough adjacent a front end opening for loading and unloading the floppy disk to the floppy disk containing space. The driver casing further has sealing elements for closing cable holes formed in the bottom plate and other gaps for blocking air flows from outside into the floppy disk containing space through the cable holes and gaps.

    摘要： A high-density flexible disk capable of accessing a large-capacity flexible disk is provided with a large-capacity detecting switch. The large-capacity flexible disk has a case accommodating a magnetic disk medium, with the case being provided with a write protection hole and a single large-capacity identifier hole formed in a vicinity of the write protection hole for distinguishing the large-capacity flexible disk from a small-capacity and a medium-capacity flexible disk. The large-capacity detecting switch of the high-density flexible disk is provided at a position corresponding to the large-capacity identifier hole for detecting the large-capacity identifier hole when the large-capacity flexible disk is inserted into the high-density flexible disk drive. In a preferred embodiment, the large-capacity detecting switch is integrally formed in a single unit with a write control switch for detecting open and close states of the write protection hole.

    摘要： In a servo writer for writing servo data on a magnetic disk medium of a large-capacity flexible disk using a magnetic head, the servo writer includes a direct-acting head carriage for supporting the magnetic head. The direct-acting head carriage is used in a high-density type flexible disk drive for carrying out data recoding and reproducing operations to and from the magnetic disk medium of the large-capacity flexible disk. A connection rod integrates the direct-acting head carriage with an actuator of the servo writer.

    摘要： A high-density flexible disk drive includes a main electromagnetic shielding plate and an auxiliary electromagnetic shielding plate. The main electromagnetic shielding plate serves as a cover member for the disk drive, and protects the whole upper surface of a large-capacity flexible disk received in the disk drive, a carriage and a linear motor from electromagnetic noise coming toward the flexible disk, the carriage and the linear motor from the upper side of the disk drive. The auxiliary electromagnetic shielding is attached to the main electromagnetic shielding plate and is smaller than the main electromagnetic shielding plate. The auxiliary electromagnetic shielding plate is arranged and located so as to protect or shield a magnetic head from electromagnetic noise coming toward the magnetic head from the upper side of the disk drive.

    摘要： A movable member 35 is moved back or forth by a motor 33. A carriage opening/closing member 41 which vertically guides a pair of projections 40 opposingly formed on opposed faces is disposed between upper and lower carriages 36 and 37 which are elastically supported on the movable member 35 and vertically opposed to each other. Reading/writing heads 19 which are opposingly disposed on the opposed faces of the upper and lower carriages 36 and 37 are separated from magnetic data recording surfaces 7 of a magnetic data recording medium 6. When the carriage opening/closing member is moved in a direction opposite to the above, the upper and lower reading/writing heads 19 are contacted with the magnetic data recording surfaces 7 by a predetermined load pressure.

    摘要： A disk cartridge includes a jacket body having upper and lower shells for receiving a magnetic disk medium therethrough. Upper and lower liners are adhered to inner surfaces of the upper and lower shells for removing fine dust attracted to upper and lower surfaces of the magnetic disk medium. In addition, upper and lower head windows are provided in the upper and lower shells, respectively, for permitting magnetic heads to access the magnetic disk medium when the magnetic disk medium is inserted through the upper and lower shells of the jacket body. A distance h1 is less than a distance h0, where h1 is the distance between said upper and said lower liners at a periphery of the upper and the lower head windows at least on an upstream side of the upper and the lower head windows with respect to a rotating direction of the magnetic disk medium, and h0 is the distance between the upper and the lower liners in a remaining area.
