Abstract

PURPOSE:To reduce the longitudinal size of a shroud which contains plural magnetic disks at a narrowed interval as much as possible by supporting magnetic heads at different cylinder positions of corresponding tracks of the upper and lower magnetic disks with an access arm. CONSTITUTION:A thin-plate spring part 6a which supports a magnetic head 5b positioned facing up and a thin-plate spring part 6b which supports a magnetic head 5a positioned facing down are fitted in parallel in a groove 15 formed atop of the access arm 7 and fixed with caulked pins 13. Consequently, the magnetic disks 4b and 4a are set only at an interval corresponding to the widths 11 and 10 of the magnetic heads 5a and 5b respectively. The longitudinal size of the shroud which contains, specially, plural magnetic disks is reduced greatly and the thickness of the device is reduced greatly.

Now, in the magnetic head support mechanism of the magnetic disk device according to the prior art, as shown in FIG. 2 when viewed from the sectional direction A-A in FIG. A magnet is placed on the same cylinder so that the magnetic field is positioned. This is because, for example, the magnetic disk 4 at the lowest position is used as a servo disk. For this reason, in the conventional magnetic disk device, since the magnetic head 7 is provided on the same cylinder, the distance 10 and 11 where the magnetic head 5 is arranged at the minimum, and the distance between the magnetic head 5 and the magnetic head 5 are set. In this case, a space 12 is required to prevent the magnetic heads 5 from colliding with each other. For this reason, it is necessary to increase the distance between the magnetic disks 4, resulting in a problem that the vertical dimension X of the sea loud 110 shown in FIG. 1 becomes redundant.
