Filed: 1985-10-02
Abstract: PURPOSE:To ensure stable reading and writing actions with a magnetic head by providing a venthole to an inner wall formed along the outer circumference edge of a magnetic disk plate of a protection cover and also forming an air path between the outer and inner walls to communicate partially with the outside via an air filter. CONSTITUTION:A magnetic head 4 reads and writes data on a magnetic disk plate 1 which is rotated by a magnetic disk drive motor 3 via spindle 2. Then the clean air 8 supplied from an air filter 9 flows onto the plate 1 through a venthole 17 of the spindle 2 and between the head 4 and the plate 1. Then the air 8 flows out to the outside 6 in the form of an air current 15 from the inner wall of a protection cover 7 through an air path 13. Thus no air circulation is produced within the cover 7 and therefore a stable air flow is supplied to both the head 4 and the plate 1. This ensures the stable reading and writing actions.
