Title: Mostafa Mahmoudian: Innovator in Magnetic Head Testing
Introduction
Mostafa Mahmoudian is a notable inventor based in San Carlos, CA (US). He has made significant contributions to the field of magnetic head testing, holding a total of 6 patents. His innovative approaches have advanced the technology used in disk drives, enhancing their performance and reliability.
Latest Patents
One of his latest patents is titled "Method and apparatus for testing magnetic heads and hard disks." This invention provides a method and apparatus for start-stop testing magnetic heads and hard disks in a real disk-drive environment. The tester is designed to have dimensions similar to a conventional disk drive, ensuring that the rotation of the disk pack generates the same aerodynamic conditions as in an actual disk drive. An accurate head positioning system is integrated within the tester housing, allowing for precise measurements of friction and sticking forces until the moment of a physical crash occurs. The combined measurement and positioning systems utilize a Hall-effect sensor attached to the voice coil, which is a common component in disk drives.
Another significant patent is the "Apparatus and method for testing magnetic disk drive components." This apparatus includes a translational slide and a rotatable arm that allows for the testing of magnetic heads interacting with magnetic disks. The design enables the magnetic head to move horizontally, rotationally, and vertically, controlled by servomechanisms. A read/write amplifier circuit is connected to the head under test, and the entire test apparatus is managed by a computer interface.
