Probabilistic Analysis of Off-Track Capability Assuming Geometric Track Misregistration Model for Higher Track Density Disk Drives

IEEE Transactions on Magnetics, 2009
Head offset capability is a key parameter for achieving higher track density. We analyze it by using a probabilistic approach. The error rate in head offset positions is calculated using core width of write and read head and mechanical runout. The nonrepeatable runout (NRRO) experiment shows the reasonableness of a Gaussian distribution assumption. The

Optimal track-following design for the highest tracks per inch in hard disk drives

2001
Summary: This paper presents an optimal track-following control design procedure that can find the theoretical highest Tracks Per Inch (TPI) achievable in hard disk drives. By formulation of the hard disk drive servo system into an \(H_2\) optimal control problem, achieving the highest achievable TPI is equivalent to minimizing the corresponding \(H_2\)
