The practical approach is to integrate a laser and optical system (waveguide and aperture) into the magnetic recording head and engineer an efficient coupling of the laser energy into the media. A whole new class of magnetic materials must also … Read more

Patterned media technologies involve a photolithographic patterning of the recording media. This patterning allows the head placement during operation to be physically pre-printed on each disk, reducing drive manufacturing costs. Traditionally, the magnetic servo pattern in a drive has to … Read more

Planar PMR disks consist of a stack of thin layers deposited sequentially across the entire disk surface in a vacuum system. Each layer performs a specific function to ensure vertical media orientation and magnetization perpendicular to the plane of the … Read more
