Abstract
A disk drive head disk assembly having a compact configuration includes an actuator assembly mounted to a base plate through a three point mounting system. The actuator includes a voice coil which engages a magnet assembly having an integrated latch/magnet spacer including a fixed magnetic latch and cantilevered beam crash stop. A single piece tape seal having a thick adhesive formed on a tape substrate encompasses the junction between the base and cover of the head disk assembly providing a substantially airtight seal to thereby maintain a desired clean environment within the disk drive.
