Hard Magnetic Material for Perpendicular Magnetic Anisotropic Field in Electromagnetic Actuator Fabrication
This paper describes a high power electromagnetic microactuator fabrication method that combines the hard magnetic Fe/Pt process, Ni/Fe permalloy magnetic circuit design, bulk micromachining, and excimer laser ablation. The hard magnetic material Fe/Pt is deposited under low temperature less than 300◦C by sputter onto a suspension diaphragm to produce a perpendicular magnetic anisotropic field....
متن کاملTechnological impact of magnetic hard disk drives on storage systems
Magnetic hard disk drives have undergone vast technological improvements since their introduction as storage devices over 45 years ago, and these improvements have had a marked influence on how disk drives are applied and what they can do. Areal density increases have exceeded the traditional semiconductor development trajectory and have yielded higher-capacity, higherperformance, and smaller-f...
متن کاملEmerging Trends in Data Storage on Magnetic Hard Disk Drives
11 INTRODUCT ION The magnetic hard disk drive (HDD) plays an important and extremely useful role in every information processing system; in fact this role is constantly growing as a result of advances in capacity, performance and price. Since the first HDD was introduced in 1956, this device has been the recipient of significant additional technology innovations which have extended its value. I...
متن کاملModeling Hard-Disk Power Consumption
Excessive power consumption is a major barrier to the market acceptance of hard disks in mobile electronic devices. Studying and reducing power consumption, however, often involves running timeintensive disk traces on real hardware with specialized power-monitoring equipment. This paper presents Dempsey, a disk simulation environment that includes accurate modeling of disk power consumption. It...
متن کاملHard Disk Drive via LMIs
In this paper, and mixed / controllers are designed for a hard disk drive (HDD) using linear matrix inequalities (LMIs). In the proposed algorithm, the problem of minimizing track misregistration (TMR) in the presence of unmodeled dynamics of voice-coil motor (VCM) is formulated as robust and mixed / problems. Additional stack variables are introduced to characterize and performances. The simul...
