Head-slider including a low-surface-energy film that prevents lubricant accumulation, head-arm assembly including the head-slider, and hard-disk drive including the head-arm assembly |
摘要 |
The head-slider is configured to receive an air-stream produced by rotation of a magnetic-recording disk and is configured to fly in proximity with a recording surface of the magnetic-recording disk. The head-slider includes a trailing edge on an outflow side of the air-stream, and a disk-facing surface that is configured to face the recording surface of the magnetic-recording disk. A low-surface-energy film is disposed on a portion of a trailing-edge side of the head-slider that is in contact with a boundary between the trailing edge and the disk-facing surface. The low-surface-energy film has a lower surface energy than other portions of the trailing-edge side where the low-surface-energy film is not disposed. |
