Tape Based Magnetic Recording: Technology Landscape Comparisons with Hard Disk Drive and Flash Roadmaps

This paper describes the areal density (bits per unit area) roadmap goals for tape based magnetic recording (TAPE) and uses these goals as counterpoints for the areal density roadmap strategies for Hard Disk Drive (HDD) and NAND flash. Technology comparisons described in this paper will show that presently volumetric densities (bits per unit volume) for TAPE, HDD, and NAND are similar and that ...

Hard 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...

Beam Deflectors for Magneto-Optical Recording Heads

Nonmechanical beam deflectors, particularly acousto-optical and electro-optical deflectors, are being considered for the access and tracking functions of a magneto-optic recording head. In this report, the suitability of electro-optic deflectors for these functions is explored. For applications requiring modest deflection, electro.optic deflectors require less power and exhibit higher optical t...
