Abstract
Disclosed is a magnetic head support assembly for a floppy disc device, in which the pressure of a spring to a magnetic head against a floppy disc is finely adjusted so as to apply a predetermined pressure thereto and to obtain an excellent contact condition between the magnetic head and magnetic disc.
Claims5
A head supporting assembly able to read data from and write data on either side of a disk having two sides, comprising:
- a pair of head means for reading data from and writing data on both sides of the disk;
- a pair of flexible head supporting plates for movably supporting the head means, respectively;
- a pair of head supporting means, opposed to each other, each for supporting one of the head supporting plates, at least one of the head supporting means being pivotable toward and away from the other head supporting means;
- a pair of pivot spring means, each mounted on one of the head supporting means, for supporting the head supporting plates;
- pressure spring means for forcing the head supporting means so that in one of the reading and writing operations the head means contact the disk;
- in one of the reading and writing operations, the flexible head supporting plates and the pivot spring means bend and provide first pressing forces for maintaining close operative relation between the head means and the disk;
- adjusting spring means for providing a second pressing force with the pivot spring means, the adjusting spring means having higher flexibility than that of the pivot spring means;
- and
- pressure adjusting means for finely adjusting the first pressing forces for the head means by adjusting the second pressing force.
