    摘要: A magnetic head for use in a perpendicular recording system having a novel shield structure that provides exceptional magnetic shielding from extraneous magnetic fields such as from a write coil, shaping layer or return pole of the write head. The shield structure is constructed to have a bottom or leading surface that is generally coplanar with the bottom or leading surface of the shaping layer, but all or a portion of the shield structure is not as thick as the shaping layer so as to have a top surface that does not extend to the same elevation (in a trailing direction) as that of the shaping layer. Making the shields extend to a lower level than the shaping layer improves magnetic performance by reducing flux leakage from the write pole, and also provides manufacturing advantages, such as during the manufacturing of the write pole. These manufacturing advantages include the advantage of having the shields covered with a protective layer of, for example, alumina during the ion milling of the write pole.

    摘要: A nipple assembly for a nursing bottle includes a nipple having a slit at the bottom of a concave depression in its tip acting as a fluid outlet valve. The nipple includes a flange seated on the rim of the bottle and held in place by a cap having a central opening through which the nipple extends. A threaded ring on the cap engages the threaded bottle neck with the outer circumferential edge of the nipple's flange compressed between the annular top and the rim of the bottle. The nipple flange includes vent apertures between its inner and outer circumferential edges, and a raised annular bead between its inner circumferential edge and the aperture. The annular bead provides a seal between flange and the cap that prevents fluid from leaking out the vent apertures when air pressure within the bottle is not substantially lower than ambient air pressure. When the air pressure inside the bottle falls below ambient air pressure as the infant suck fluid from the bottle, the annular bead moves away from the cap to break the seal, thereby permitting air to pass through the central opening and into the bottle via the vent apertures. The nipple includes one or more raised annular beads to provide tactile stimulation to a nursing infant and to improve the seal between the infant's lips and the nipple body to limit fluid leakage.

    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: A method of fabrication of the write head of a perpendicular recording head allows for production of P3 pole tips of width less than 200 nm (200×10−9 meters). The method includes fabricating the P2 flux shaping layer, depositing the P3 layer, depositing a layer of ion-milling resistant material, depositing at least one sacrificial layer, shaping the P3 layer into P3 pole tip, removing the at least one sacrificial layer to leave the P3 pole tip, and encapsulating the P3 pole tip.

    摘要: A multi-step process for notching the P1 pole of the write head element of a magnetic head. In a first step following the fabrication of the P2 pole tip, a layer of protective material is deposited on the approximately vertical side surfaces of the P2 pole tip. Thereafter, a first ion milling step, utilizing a species such as argon, is performed to mill through the write gap layer and to notch into the P1 pole layer therebelow. The removal of redeposited material from the side surfaces of the P2 pole tip is thereafter accomplished and the protective material formed on the side surfaces of the P2 pole tip protects the P2 pole tip during the redeposition clean up step. Thereafter, the protective material is removed from the side surfaces of the P2 pole tip, and a second ion milling step is performed to further notch the P1 pole material.

    摘要: One preferred method for use in making a magnetic write head with use of the resist channel shrinking solution includes the steps of forming a first pole piece layer of a first pole piece; forming a gap layer over the first pole piece layer; forming a patterned resist over the first pole piece layer and the gap layer; electroplating a first pedestal portion of a second pole piece over the gap layer within a channel of the patterned resist; forming an oxide layer over the first pedestal portion; applying the resist channel shrinking solution comprising the resist channel shrinking film and the corrosion inhibitors over the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel; removing the resist channel shrinking solution; electroplating a second pedestal portion of the second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the structure. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pole piece during the act of baking the resist channel shrinking solution.

    摘要: A method for reducing plated pole height loss in the formation of a write pole for a magnetic write head is disclosed. The method includes forming a conductive layer on a thin film substrate, forming a photoresist layer on the conductive layer and forming a trench in the photoresist layer. A thick seed layer is then placed on the trench and on the photoresist layer surface using a collimator. Moreover, the process includes plating while applying a voltage to the thin film substrate where the electrically isolated seed layer is removed and the trench is filled with plating material, removing the photoresist layer, and removing the exposed portions of the conductive layer on the thin film substrate.
