Disk drive apparatus, hard disk drive, and enclosure for hard disk drive |
摘要 |
To restrain a flutter of a magnetic disk in a high-speed hard disk drive, a ramp 40 is provided so as to be separated with a predetermined space from a side wall 12a of a base 12. Between the side wall 12a and the ramp 40 is formed a bypass channel 42. An air flow is supplied toward a magnetic disk 22 through the bypass channel 42. By using such a configuration, a flutter of the magnetic disk 22 is reduced.
