Patents by Inventor Isabel Goncalves Trindade

Isabel Goncalves Trindade has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Magnetic read head wherein the shields are used as electrical leads and have a minimized anisotropic magneto-resistance effect
    Patent number: 6807032
    Abstract: A ferromagnetic shield material having a minimized anisotropic magneto-resistance effect permits the use of a combined shield/electrical lead for magneto-resistive read elements. The shields/electrical leads may therefore be placed closer together, maximizing the recording density that may be read by a magnetic recording head using a read element having such shields/leads.

  • Perpendicular recording head having integrated read and write portions
    Patent number: 6621664
    Abstract: An integrated read/write perpendicular recording head facilitates the use of magnetic storage media having a high magnetic recording density and high data rates. The use of a perpendicular write portion provides adequate space between the main and opposing poles for a read element and associated electrical contacts therebetween. The use of a differential dual spin valve as a read element eliminates the need for magnetic shielding of the read element. Such a structure permits the read element and main write pole to be close together, thereby minimizing seek time, and permitting rapid transition from read to write operations, and vice versa.
