Abstract:

A precisely machined test nest holds a single hard disk drive slider. The test nest is fabricated to contain a micro pickup coil that is positioned to be able to detect magnetic flux from a write element of the slider. The micro pickup coil has highly repeatable and controllable positioning with respect to the write element. This technique also allows local magnetic field to be applied to the read element, and its small size allows excitation at higher frequencies than are currently achievable today. The coil is lithographically defined and integrated into the test nest and used on single slider testers. The low inductance of the coil allows it to be driven at high frequencies. Its position within the test nest ensures good heat sinking and enables large current pulses to be employed.

Abstract:

Embodiments disclosed herein relate to communication of a task-related request from a requester to service providers. The task-related request may specify a set of parameters, including a task completion location and a representation of the task related request. The service providers may be differentiated based on distance from each service provider to the requester. A price quote may be aggregated from each service provider with the distance from that service provider to the requester and related publicly-available ratings and reviews for that service provider to generate a service provider score for that service provider. Upon receiving corresponding input from the requester, selection of an optimal service provider may be made from the service providers according to its total service provider score. Tracked movement of the optimal service provider from its initial start location to the task completion location may be displayed to the requester.
