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.

Abstract: A transparent plastic tag holder attachable to a peg board hanger employed to support a plurality of packages of goods for sale, the tag holder being a flat T-shaped strip of two or more plastic sheets heat sealed to each other around their common perimeter, an elongated arm and a cross arm forming the T-shaped strip, a pair of spaced circular passageways at the free end portion of the arm to receive legs of the hanger, a slot adjacent the other end of the arm to receive the free end of the hanger, and the cross arm having a pocket therein disposed generally downwardly from the free end of the hanger and adapted to receive and maintain an identification tag. The tag holder includes another passageway generally between the pair of spaced passageways for attachment to a guarded J-hook hanger.
