Described herein is a magnetic storage device that includes at least one magnetic disk, at least one armature rotatably movable relative to the at least one magnetic disk, and a transducer head coupled to the armature. The magnetic storage device further includes a stiffener that is coupled to the armature. The stiffener includes at least one arm having a flexible printed circuit board (FPCB) portion and a deflection portion angled relative to the FPCB portion. The magnetic storage device also includes an FPCB coupled to the stiffener.

A bulk erase tool for erasing perpendicularly recorded media is provided. The bulk erase tool includes a first polarity erase magnet and a second polarity erase magnet offset from the first polarity erase magnet. In so doing, the offset between the first polarity erase magnet and the second polarity erase magnet produces a non-parallel non-vertical applied field utilized for erasing perpendicularly recorded media.

A method for utilizing a bulk erase tool to erase perpendicularly recorded media is provided. A bulk erase tool having a first polarity erase magnet and a second polarity erase magnet is received. An offset is provided between the first polarity erase magnet and the second polarity erase magnet, wherein the offset provides a non-parallel non-vertical applied magnetic field suitable for erasing perpendicularly recorded media.

A spindle motor for implementation in a low profile hard disk drive is described; that spindle motor having a novel configuration for the torque generating portion. The spindle motor includes a hub coupled with a disk platter; that has a rotational axis about a suitable bearing system. A stator portion of material for conducting magnetic flux from the rotor poles, and having twelve stems and a plurality of windings, is configured to be disposed beneath the disk platter and coupled to the drive base. A rotor portion coupled with the hub having back iron ring with a permanent sixteen pole magnet radially polarized is closely radially disposed to the stator. The number of poles of the rotor portion has a defined proportion relative to the number of stems of the stator portion. The windings provide conductivity for creating an electromagnetic force applicable at the torque radius for rotation of the hub.
