Patent number: 8116075Abstract: A system and method for an improved multiple hard-disk-drive data-storage enclosure. Some embodiments position drives in counter-rotating pairs, each simultaneously accessing half the data, such that seek-caused actuator rotational-acceleration vibration cause simultaneous canceling rotational torque. Some embodiments position the edge of a first drive (or drive pair) at an angle to the actuator midpoint of a nearby second drive (or drive pair), such that rotational-acceleration vibration from a seek-caused actuator rotation in the first drive does not cause a rotational movement into the second drive that affects the tracking or seek operation. Some further embodiments position drives in a herringbone pattern to redirect air flow in addition to reducing rotational-acceleration vibration interaction. Other embodiments include a printed wire circuit board mounted to reduce the rotational-acceleration vibration interaction.Type: GrantFiled: April 19, 2010Date of Patent: February 14, 2012Assignee: Assurance Hardware and Software Solutions LLCInventors: Jonathan E.

Patent number: 5134530Abstract: An air stripper for stripping air in a head disk assembly within a magnetic disk drive. The head disk assembly includes a spindle, a magnetic disk, a head arm and the air stripper. The magnetic disk is secured to the spindle for rotation about a central axis and includes a generally planar surface between an inner disk diameter and an outer disk diameter. Rotation of the disk causes a volume of air adjacent the disk surface to flow in the direction of disk rotation. The head arm is positioned proximate the disk surface for actuation across the disk surface through the volume of air. The air stripper is positioned proximate the disk surface and upstream from the head arm with respect to the direction of air flow. The air stripper extends into the volume of air for generally uniformly stripping air such that rotational velocity of the disk is substantially unaffected by actuation of the head arm across the volume of air.Type: GrantFiled: August 10, 1990Date of Patent: July 28, 1992Assignee: Seagate Technology, Inc.Inventor: Jonathan E.
