Abstract
A laminated suspension includes recesses in one layer of the suspension that aid in attaching elements to the suspension and in utilizing a micromotor placed on the suspension. In particular, examples of the recesses include weld areas for welding the suspension to other items, fiducials that are used to align the suspension with other items, micromotor recesses that receive the micromotors, adhesive controls that restrict the location of adhesives on the suspension, electrical interconnect attachment tabs that accept flex electrical circuits, side rails that reduce torsional resonance during microactuation and microactuator hinges that reduce the force needed for microactuation. In addition, a laminated suspension with a single metal layer in the spring area is provided.
Claims29
A data storage device for storing and accessing data in tracks on a medium, the storage device having a laminated suspension constructed of at least two material layers, the laminated suspension comprising:
- a base area,
- a spring area;
- a load beam;
- and
- an attachment aid area formed as a recess in one but not all of the material layers of the laminated structure, wherein the attachment aid area is located within one of the base area, spring area, or load beam and aids in the attachment of an item to the laminated suspension.
A laminated suspension for a data storage device, the laminated suspension formed of at least two layers and comprising:
- a base;
- a load beam;
- at least one micromotor positioned between the base and the load beam that is capable of moving the load beam relative to the base;
- and
- a microactuation recess formed in one layer of the suspension laminate that assists in microactuation of the suspension.
A method of manufacturing a suspension for a disc drive, the method comprising:
- bonding a first layer of material to a second layer of material;
- removing a portion of the second layer of material to expose the first layer of material thereby defining an attachment aid area that aids in attaching an item to the suspension.
A disc drive for storing data on a disc, the disc drive comprising:
- a laminated suspension having a base area, a load beam and a micromotor positioned between the base area and the load beam, and
- microactuation means for assisting in microactuation of the load beam relative to the base area, the microactuation means formed as a recess in one layer of the laminated susupension.
A data storage device for storing and accessing data in tracks on a medium, the storage device having a suspension comprising:
- a base area formed of a first metal layer bonded to a second metal layer by an adhesive;
- a spring area formed of only a single metal layer;
- and
- a load beam formed of a first metal layer bonded to a second metal layer by an adhesive.
