言う問題点を有していた。 Now, the magnetic head support mechanism of the magnetic disk device according to the prior art has a magnetic head for the upper surface of the magnetic disk 4 and a magnetic head for the lower surface, as shown in FIG. 2 when viewed from the sectional direction A-A' in FIG. are arranged in alignment in the direction perpendicular to the recording surface of the magnetic disk 4. For example, this is the magnetic disk 4 at the lowest position.
This is because it is used as a servo disk. Therefore, in the conventional magnetic disk device, all the magnetic heads 5 are arranged in a line in a direction perpendicular to the surface of the magnetic disk 4, so that the minimum distance between the magnetic heads 5 is 10 and 11. Furthermore, a space 12 is required to prevent the magnetic heads 5 from colliding with each other when the magnetic heads 5 slide. For this reason, it is necessary to provide a large interval between the magnetic disks 4, resulting in a problem in that the vertical dimension X of the shroud 110 shown in FIG. 1 becomes redundant.
