    摘要: In the engaging structure of a lead screw (51) with a head lift body (52), for simplification of a feeding side mechanism and improvement of feeding accuracy, the head lift body has only one fingernail shaped protrusion (551) as a member engaging with an external thread of the lead screw (51). The protrusion (551) is provided on an internal wall surface of a bearing portion (55) formed in an integral structure with the head lift body (52). Accordingly, the engagement of the external thread of the lead screw and the single protrusion converts the rotation movement of the lead screw (51) to the linear movement of the head lift body (52). As a result, a feeding accuracy in the linear movement converted from the rotation movement is only determined by a feeding accuracy of only the lead screw (51). In an example, the protrusion is a half-moon shaped plate.

    摘要: In a reel hub releasing mechanism, a seesaw type release lever is arranged so as to be turnable with its central part as a fulcrum, and it includes first and second flat members extending onto both sides from the fulcrum. The first flat member has an engaging protrusion at its distal end, while the second flat member has at its distal end a lever manipulating protrusion which protrudes upwards in order to manipulate a lock lever. A tape cartridge is formed with a window for snugly inserting the lever manipulating protrusion. When the lever manipulating protrusion abuts against the lock lever through the window, the operation of releasing reel hub lock is effected, and the tape cartridge is positioned so that the position of the window in the direction of inserting the tape cartridge into the slot of a tape drive may become substantially equal to the position of the lever manipulating protrusion in the inserting direction. It is accordingly possible to provide that reel hub lock mechanism of the tape drive which can position the tape cartridge simultaneously with the release of the reel hub lock, without separately forming any positioning part, and the tape drive which comprises the reel hub lock mechanism.

    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 method of carrying out defect management on reading data from a disk-shaped magnetic recording medium comprising a plurality of tracks separated into a user data area available to a user, an alternate area, and a management area, the method comprises the steps of retrying reading operation of data up to a maximum retry count when an error is detected on reading of data for a target sector in the user data area and of registering the target sector in a defect table in the management area and writing read-out data in an alternate sector in the alternate area in a case where a retry count is not less than a specific count when retry results in a success. Alternatively, the method comprises the steps of retrying reading operation of data up to a maximum retry count when an error is detected on reading of data for a target sector in the user data area, of overwriting read-out data in the target sector in a case where a retry count is not less than a specific count when retry results in a success, and of registering the target sector in a defect table in the management area and writing read-out data in an alternate sector in the alternate area in a case where an error is detected when overwritten data is reread from the target sector.

    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.
