    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 drive 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 drive 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： The present invention aims at reducing the thickness of a floppy disk drive by minimizing a vertical movement of a floppy disk-retaining disk holder and reducing the height of a chassis. The disk holder is provided on both side surfaces of its rear end portion with support shafts, which are connected to the chassis so that the support shafts can be turned. The disk holder becomes pivotable around these support shafts as fulcrums, i.e., the front portion of the disk holder is turned vertically. The upper and lower magnetic heads are formed so that they can be engaged with and disengaged from the floppy disk in conjunction with a pivotal movement of the disk holder.

    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： 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.
