US 7,626,805 B2 · Disk-drive system supporting massively parallel video streams and method

Abstract

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.
