Spacers for end-wise pneumatic partitioned disk pack

摘要

Improved disk drive equipment is illustrated, being characterized by improved end-wise pneumatic partitioning means for deflecting selected flexible magnetic recording disks and featuring improved "external" pneumatic partition means for directing partitioning air to be injected end-wise and axially up the pack as a jet stream through bores in the disks and spacers into a gap between any two disks-these bores terminating at respective gaps where the spacer means is radially cut-out to divert the axial air stream to its associated inter-disk gap.
