摘要： A slider for use in a disk drive system with a read/write head that has a write coil as part of a write transducer. The write coil has a center tap thereon for connection to a conductor in addition to the connection of the ends of the write coil to two other conductors. This allows the write coil to be driven from opposite ends with opposite but equal currents in addition to the write currents that are used in write mode or alone in modes other than in write mode, such as just before write mode is entered. The current flowing in or out of the center tap then will be the sum of the currents flowing out or into the opposite ends of the write coil. In this manner, no magnetic fringing field is created since the currents/fields cancel each other out. Also, the power dissipation in the write coil during this time will be approximately the same as in write mode and a similar amount of pole tip protrusion should be produced thereby.

摘要： A system and method are provided for manufacturing a coil structure for a magnetic head. Initially, an insulating layer is deposited with a photoresist layer deposited on the insulating layer. Moreover, a silicon dielectric layer is deposited on the photoresist layer as a hard mask. The silicon dielectric layer is then masked. A plurality of channels is subsequently formed in the silicon dielectric layer using reactive ion etching (i.e. CF4/CHF3). The silicon dielectric layer is then used as a hard mask to transfer the channel pattern in the photoresist layer using reactive ion etching with, for example, H2/N2/CH3F/C2H4 reducing chemistry. To obtain an optimal channel profile with the desired high aspect ratio, channel formation includes a first segment defining a first angle and a second segment defining a second angle. Thereafter, a conductive seed layer is deposited in the channels and the channels are filled with a conductive material to define a coil structure. Chemical-mechanical polishing may then be used to planarize the conductive material.

摘要： The present invention is directed to carrying out a high density magnetic recording to a material having a large coercive force by perpendicular magnetic recording head.By giving a patterning onto a soft magnetic under layer of a perpendicular two-layer recording media in sync with a period of a recording bit, a magnetic field from a write head can be allowed to converge to a soft magnetic column. Therefore, a magnetization reversal of the magnetic recording media material having a large anisotropic constant becomes possible, and then a high density magnetic recording can be achieved.
