SYSTEM AND METHOD FOR MASS STORAGE USING MULTIPLE-HARD-DISK-DRIVE ENCLOSURE

摘要

A system and method for an improved multiple-hard-disk-drive data-storage enclosure (1400). 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) (1120) at an angle to the actuator midpoint of a nearby second drive (or dri ve pair) (120), such that rotational-acceleration vibration from a seek-caused actuator rotation in the first drive does not cause a rotational movement in to the second drive that affects the tracking or seek operation. Some further embodiments position drives (120, 1120) 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.
