The present disclosure provides a vibration damper for an actuator assembly. One exemplary embodiment relates to an actuator assembly including a magnetic assembly configured to produce a magnetic field and an actuator movable relative to the magnetic assembly in response to the magnetic field, wherein the actuator includes a vibration damper which interacts with the magnetic field.

The present invention is a system for stiffening a voice coil of a magnetic disk drive. One embodiment of the present invention are stressed skins that interconnect with an upper portion and a lower portion of the voice coil such that they are flush with the upper and lower surfaces of the voice coil. The stressed skins are adhered or otherwise interconnected to the voice coil thus allowing for bending, twisting, torsional, and various other loads that generate vibrations that affect the head of an actuator assembly to be dampened. One embodiment of the present invention includes two stressed skins interconnected to a voice coil constructed of carbon composite wherein the space therebetween is filled with a foam to provide additional stiffness and damping.

A tape drive ( ) that includes a cartridge receiver ( ), a take-up reel ( ) and a drive leader ( ) is adapted for use with a cartridge ( ) that includes a cartridge leader ( ) having a cartridge buckle component ( ). The drive leader ( ) includes a drive buckle component ( ) that engages the cartridge buckle component ( ) to couple the drive leader ( ) to the cartridge leader ( ). The drive leader ( ) includes a leader connector ( ) having a connector aperture ( ). The take-up reel ( ) includes a hub ( ) that receives the drive leader ( ). Uniquely, the hub ( ) including a drive component channel ( ) that is sized and shaped to receive the drive buckle component ( ). Preferably, the hub ( ) also includes a cartridge component channel ( ) that is sized and shaped to receive the cartridge buckle component ( ) and a pair of member channels ( ) ( ) for receiving the leader connector ( ). With this design, the surface of the storage tape ( ) that is being wound around the take-up reel ( ) is substantially a uniform distance from an axis of rotation ( ) of the take-up reel ( ). This reduces the amount of wear of the storage tape ( ) and reduces speed variations caused by winding the tape ( ) onto an eccentric surface.
