Appl. No.:

09/934096

Inventors:

Lujun Chen - West Hills CA
James Giusti - Chanhassen MN
Jian Chen - Shakopee MN
Sining Mao - Savage MN

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5127

US Classification:

360319

Abstract:

A magnetoresistive (MR) sensor for use in a magnetic storage system including a magnetic storage media having multiple concentric microtracks with information stored thereon. The MR sensor includes a plurality of generally parallel layers that form an MR stack. The MR sensor also includes a top shield and a bottom shield that are spaced apart on opposite sides of the MR stack in a longitudinal direction. The Mr sensor further includes a first and a second side shield spaced apart on opposite sides of the MR stack in a transverse direction. The top shield, bottom shield, first side shield and second side shield substantially surround the MR stack.

International Classification:

G02B006/00

US Classification:

385140, 385134

Abstract:

In a preferred embodiment, a motorized variable optical attenuator comprises an input fiber collimator; an output fiber collimator disposed substantially along the first collimator; and a right-angle reflector movable relative to the input collimator and the output collimator along a translation direction forming a non-zero angle with a direction of a light beam emitted by the input collimator. The reflector comprises two mutually-perpendicular reflective surfaces for sequentially reflecting the light beam emitted by the input collimator to the output collimator. A variable attenuation imparted by the attenuator on the light beam is determined by a position of the reflector relative to the input collimator and the output collimator, along the translation direction. The reflector preferably comprises a right-angle prism adhered to a nut mounted on a threaded axle driven by a stepper motor. The attenuator can achieve stable, ripple-free attenuation characteristics at insertion losses beyond −40 dB.
