An HGAs carrier station receives HGAs to be tested. An alignment station on the base includes an alignment surface which selectively rotates about an alignment axis. A camera generates images of an HGA on the alignment surface, which is rotated so that the HGA has a desired spatial orientation which is maintained as the HGA is transferred to an HGA testing workstation. A received, oriented HGA is positioned to enable read/write test operations on a disk rotating on an adjacent spinstand. To effect the successive position operations, a transporter includes a track overlying the workstations, and a carriage movable along the track, to pass from workstation to workstations. The loader is automatically operative under the control of a controller."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"HGA loader with optical alignment for automated magnetic head testing","description":"An HGA loader provides HGAs, in succession, to a multiple workstation head tester.
