Abstract
A baffle assembly comprises a series of parallel baffle plates positioned adjacent to and coplanar with the respective disks mounted on a spindle of a disk drive. The baffle plates help maintain parallel air flow across each disk edge thereby reducing turbulence at the disk edge. This reduces the vertical vibratory motion of the positioning arm holding the transducer head slider suspension assembly which in turn reduces the horizontal or cross-track motion of the head.
