ABSTRACT:
An integrated head-suspension-wick system having lubrication, including a bearing area at one end that holds a magnetic transducer against the disk. The invention provides wicking grooves in the integrated head-suspension-wick arm. The grooves are shaped to cause capillary forces to pull the lubricant from the supply wick on the arm, along the suspension of the bearing area. This ensures that the disk area under the head will not go dry regardless of storage duration or conditions. When the disk is running, the wick continues to conduct lubricant to the disk surface.
