Performance analysis of magnetic recording systems

Abstract—Approximations to the union bound performance of sequence detection in the presence of colored noise and an algorithm to compute bit error and error event probabilities are presented and compared to bitby-bit simulation results. These computations, which are very accurate at bit error probabilities , are then used to analyze the performance of standard and reverse concatenated Reed-Sol...

Paleomagnetic recording fidelity of nonideal magnetic systems

A suite of near-identical magnetite nanodot samples produced by electron-beam lithography have been used to test the thermomagnetic recording fidelity of particles in the 74-333 nm size range; the grain size range most commonly found in rocks. In addition to controlled grain size, the samples had identical particle spacings, meaning that intergrain magnetostatic interactions could be controlled...

Timing Recovery in Magnetic Recording Systems

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 proce...

Distributed Systems and Multi-Point Video Recording

II. BACKGROUND Abstract: This paper describes the application of distributed system techniques to an MIT Media Lab sponsored project on multi-point video recording. The two main improvements to the system are: (1) An algorithm to calculate optimum camera angle based on the locations of other cameras in the system and (2) A method of forwarding information between out-ofrange cameras via interme...
