Described herein is a disk drive having a head stack assembly with an actuator arm that is rotatable about an axis of rotation and has a damping layer disposed on the actuator arm. The apparatus primarily includes a frame member which defines a plurality of bays arranged in a single line for containing the EPLs. The communication between the client and the group is standards based. If no idle channel is available, the switch determines whether a remote user device with a lower priority than the requesting remote user device is using a channel. The basic image and the basic presentation are thereby simultaneously output by the computer, but spatially separate from one another.
