| 8218263 | Write head with different upper and lower yoke lengths and methods for making the same According to one embodiment, a system comprises an upper yoke having a first length defined between a pole tip thereof and a back gap thereof. In addition, the system includes a lower yoke having a second length defined between a pole tip thereof and a back gap ther... | 07/10/2012 |
| 8201320 | Method for manufacturing a magnetic write head having a wrap around shield that is magnetically coupled with a leading magnetic shield A method for manufacturing a magnetic write head having a leading magnetic shield and a trailing magnetic shield that are arranged to prevent the lost of magnetic write field to the trailing magnetic shield. The write head includes a non-magnetic step layer that pro... | 06/19/2012 |
| 7933096 | Layered return poles for magnetic write heads Methods and structures for the fabrication of both thin film longitudinal and perpendicular write heads are disclosed. A unique feature of these write heads is the inclusion of layered return poles, which comprise alternating layers of 22/78 and 80/20 NiFe alloys. T... | 04/26/2011 |
| 7748103 | Method of manufacturing a perpendicular magnetic recording write head with notched trailing shield A perpendicular magnetic recording write head has a write pole, a trapezoidal-shaped trailing shield notch, and a metal gap layer between the write pole and notch. The write pole has a trailing edge that has a width substantially defining the track width and that fa... | 07/06/2010 |
| 7612963 | Perpendicular magnetic recording head with photoresist dam between write coil and air bearing surface A magnetic recording head for use in perpendicular magnetic recording having a design that allows the write coil to be manufactured by a damascene process for increased coil pitch and reduced coil resistance. The magnetic write head includes a photoresist dam struct... | 11/03/2009 |
| 7576951 | Perpendicular magnetic write head having a magnetic write pole with a concave trailing edge A magnetic write head for perpendicular magnetic recording having a write pole with a concave trailing edge. The magnetic write pole can have a trapezoidal shape with first and second laterally opposed sides that are further apart at the trailing edge than at the le... | 08/18/2009 |
| 7509729 | Method for making a perpendicular magnetic recording write head A method for making a write pole in a perpendicular magnetic recording write head uses a metal mask to pattern the primary resist and only ion milling during the subsequent patterning steps. A layer of primary resist is deposited over the magnetic write pole materia... | 03/31/2009 |
| 7030035 | Prevention of electrostatic wafer sticking in plasma deposition/etch tools To remove unwanted electrostatic charge from a substrate or substrate clamping mechanism in a plasma processing chamber following the plasma processing of the substrate, the process of shutting down the RF power supply is altered. Specifically, the present invention... | 04/18/2006 |
| 6955747 | Cam driven paddle assembly for a plating cell The present invention overcomes the drawbacks and limitations described above by providing a paddle assembly having a paddle that moves in a bidirectional fashion for agitating solution in a container of a plating cell. A follower is coupled to the paddle. The follo... | 10/18/2005 |
| 6115200 | Method and apparatus for preventing write operations in the presence of post-shock motion The present invention is a method and apparatus for preventing a write operation to a storage medium of a data storage system in response to a shock event which excites the component modes of the data storage system. In accordance with the invention, an a... | 09/05/2000 |
