Repeatable Runout following in Bit Patterned Media Recording
نویسندگان
چکیده
An adaptive feedforward controller design for tracking repeatable runout (RRO) in bit patterned media recording (BMPR) is proposed for single stage hard disk drives (HDD). The technique is based on modified filtered-x least mean squares (MFXLMS) algorithm with deterministic periodic input, and a novel variable step size that boosts both the convergence rate and the steady state error. Comprehensive simulations and comparisons are provided to show the effectiveness of the proposed method.

DSP Implementation of a Direct Adaptive Feedfoward Control Algorithm for Rejecting Repeatable Runout in Hard Disk Drives
A direct adaptive feedforward control method for tracking repeatable runout (RRO) in bit patterned media recording (BPMR) hard disk drives (HDD) is proposed. The technique estimates the system parameters and the residual RRO simultaneously and constructs a feedforward signal based on a known regressor. An improved version of the proposed algorithm to avoid matrix inversion and reduce computatio...
متن کاملTwo-dimensional Decoding Algorithms and Recording Techniques for Bit Patterned Media Feasibility Demonstrations
Recording experiments and decoding algorithms are presented for evaluating the bit-error-rate of state-of-the-art magnetic bitpatterned media. The recording experiments are performed with a static tester and conventional hard-disk-drive heads. As the reader dimensions are larger than the bit dimensions in both the down-track and the cross-track directions, a two-dimensional bit decoding algorit...

متن کاملAnalytical read back signal modeling in magnetic recording
An analytical model for the read back signal is derived for perpendicular and longitudinal magnetic recording. The model captures the contribution of a single bit rather than the contribution of a bit transition which makes it applicable to patterned media as well as continuous media. It is based on the law of Biot–Savart and separates the contribution of the magnetic media from the head sensit...
متن کاملRecording performances in perpendicular magnetic patterned media
We report on the recording performances and signal-to-noise ratio analyses of perpendicular magnetic bit-patterned media. Two different types of magnetic samples are investigated. They differ by the way that they were patterned (nano-imprint versus e-beam lithography) as well as their magnetic properties (Co/Pt multilayers and CoCrPt alloy are the recording layers). By using a contact read/writ...
