The invention is directed to techniques for dampening vibration of a disk drive using a dampening member which is co-planar with a mid-plane of the disk drive, and which has at least a portion extending from a carrier toward a main assembly when the carrier is installed within the main assembly in order to dampen vibration of the disk drive when the disk drive is in operation. The use of the dampening member in this location results in vibration dampening which is superior to conventional disk drive mechanisms. In particular, since the dampening member is co-planar with the mid-plane of the disk drive, the dampening member dampens vibration along a critical direction providing substantial vibration isolation. Accordingly, disk drives configured in accordance with the invention are capable of providing high performance even in high rotation speed (i.e., high RPM) and high density configurations.
