  • Recording head writer with high magnetic moment material at the writer gap and associated process
    Patent number: 7688545
    Abstract: A magnetic recording head with an overall planar design and tight dimensional control of throat height and notch width is achieved below the gap. Writer poles include very high magnetic moment material on both sides of the writer gap. Additionally the pole tips are shaped to provide high field with good spatial gradient for optimal writing conditions, thereby extending the capability of longitudinal recording heads for high density and high frequency applications.

  • High gradient disc drive writer
    Patent number: 7187519
    Abstract: A magnetic writer having an air bearing surface for confronting a surface of a rotating disc is disclosed. The magnetic writer includes a bottom pole and a top pole. The top pole includes a first top pole portion and a second top pole portion connected by a top pole extension. The top pole extension, which preferably has a uniform width at the air bearing surface, orients a magnetization of the first top pole portion substantially parallel to an air bearing surface of the magnetic writer. The bottom pole includes a base pole and a notch pole. The base pole is recessed from the air bearing surface to prevent or reduce fringe erasure fields. The notch pole, which abuts the base pole and extends from the air bearing surface to at least a magnetic throat height of the magnetic writer, has a magnetization oriented perpendicular to the air bearing surface.

  • Method of forming a beveled writing pole of a perpendicular writing element
    Patent number: 7100266
    Abstract: A beveled writing pole includes a top portion, a beveled portion, and a throat portion. The top portion has an end that defines a writing pole tip. The beveled portion adjoins the top portion and has a bevel that extends from the writing pole tip and increases a thickness of the writing pole proximate the pole tip. The throat portion is formed of the top and beveled portions and has tapered sides that extend from the writing pole tip and increase a width of the writing pole proximate the writing pole tip. A method of forming the beveled writing pole is also presented.

  • Writing element with no return path
    Publication number: 20020171975
    Abstract: A writing element includes a writing pole, a conducting coil and an insulating material. The writing pole includes a pole tip and extends therefrom to a back gap region. The conducting coil includes coil segments positioned adjacent and transverse to the writing pole. The coil segments are adapted to produce magnetic signals that orient magnetization vectors at the pole tip of the writing pole in a desired direction. The insulating material is formed between the writing pole and the coil segments. Magnetic signals do not conduct to the back gap region through a return pole element.
