Timing Recovery in Magnetic Recording Systems
نویسنده
چکیده
Timing recovery is a crucial component in a magnetic recording channel detector. Conventional timing recovery techniques are sufficient only when operating at high signalto-noise ratio (SNR). However, iterative error-correction codes allow reliable operation at very low SNR, where conventional techniques fail. In this paper, we summarize the timing recovery schemes based on a per-survivor processing technique that are capable of working at low SNR. Results indicate that they perform better than conventional schemes.

Performance of Interpolated Timing Recovery in Perpendicular Magnetic Recording Channel
Magnetic recording systems employ conventional VCO-based timing recovery to synchronize the readback signal and the sampler, which is expensive to implement. To get rid of this VCO, a fully digital timing recovery known as interpolated timing recovery (ITR) is utilized. This paper investigates the performance of the ITR architecture in magnetic recording channels with and without error-control ...
متن کاملJoint Recovery of Timing and Position Information in Two-Dimensional Magnetic Recording (TDMR)
In two-dimensional magnetic recording (TDMR), bit sizes are expected to be comparable to grain sizes in order to achieve very high areal-densities. As a consequence, the channel suffers from not only severe two-dimensional (2D) interference but also from cross-track bit location errors (known as position errors) and down-track bit location errors (known as timing errors). These position and tim...
متن کاملBi-Directional Timing Recovery for Perpendicular Magnatic Recording Channels
Magnetic recording systems employ conventional timing recovery to synchronize the sampler with the readback signal. However, conventional timing recovery does not perform well when the timing error is large. This paper proposes the bi-directional timing recovery, which utilizes conventional timing recovery to sample the readback signal both in forward direction and in backward direction. The ou...
متن کاملTiming Recovery for Data Storage Systems
As magnetic recording track densities increase, signal-to-noise ratio (SNR) will decrease and as linear density increases, inter-symbol interference (ISI) will increase. One of the approaches being investigated for dealing with increased ISI and decreased SNR is based on iterative soft decoding (e.g., turbo codes and LDPC codes). However, the expected coding gains assume that the timing recover...
