Publication number: 20110292546Abstract: A patterned recording media is formed from a master template that includes a data area and a timing track area having a final timing track. In order to form the final timing track, a first timing track is etched into master template and tested for accuracy by comparing the angular position of the master template to the timing track. If errors are detected in the timing track, the errors are used to create additional timing tracks which are etched into the master template. This process of improving the timing track is repeated until a final timing track is formed that has errors below a predetermined level. The timing tracks formed prior to the final timing track are removed and the master template is used to make stampers which are used to make patterned media disks.Type: ApplicationFiled: May 25, 2010Publication date: December 1, 2011Applicant: Seagate Technology LLCInventors: Dave Marcus Tung, Sundeep Chauhan, David Kuo, Shih-Fu Lee

Patent number: 7974036Abstract: Systems and methods are provided for correcting write synchronization of a magnetic storage device with respect to magnetic storage media and its corresponding writable magnetic bits, or dots. In particular, these systems and methods involve using time-shifting principles to calibrate the magnetic storage devices to correct slow drifts of reader-writer timing. It is to be appreciated that time-shifting techniques can be applied in a variety of manners. For example, the very dots on the media can be positioned in time-shifted fashion. In another example, the writing to the dots can be time-shifted.Type: GrantFiled: August 19, 2008Date of Patent: July 5, 2011Assignee: Seagate Technology LLCInventors: Shih-Fu Lee, Alexander Y. Dobin, Dave M. Tung, David S. Kuo

Patent number: 7916308Abstract: An optical profiler for an ultra-smooth surface, such as a magnetic recording disk, provides for a normally incident beam deflection against the target surface to be profiled. A linearly polarized laser light of a first polarization is focused on the target surface in a normally incident direction. The beam is reflected back along its original path from the focal point. Optics are provided that change the polarization of the reflected beam to a second polarization. A reflected beam, with a second polarization, is directed onto a position sensitive detector for evaluation.Type: GrantFiled: November 5, 2003Date of Patent: March 29, 2011Assignee: Seagate Technology LLCInventors: Jianmin Wang, Jason L.
