Modular Digital Magnetic Recording Channel Software Simulator
Software simulations are presented for the magnetic and optical recording channels that illustrate the performances, measured in bit error rate (BER) dependence by signal to noise rate (SNR) characteristics of recording digital sequences, calculated for equalized partial response channels followed by Viterbi detection versus decision feedback equalization followed by fixed depth tree search det...
متن کاملMagnetic sound recording
The first complete magnetic recorder (wire on a drum) was constructed in 1898 by Poulsen (Denmark). In 1938 the first recorders using plastic tape with an iron oxide layer were used. Since then, magnetic sound recording has become the most popular way of storing broadcast programmes for transmission at any time. Early attempts with temporary disc recording and photographic recording proved unsu...
متن کاملMagnetic tape recording electrocardiograph.
R ECORDING the electrocardiogram for prolonged intervals presents difficulties from the standpoint of economy and convenience. One 200 foot roll of paper for a direct writing instrument is used in 40 minutes of continuous recording at 25 mm. per second, and reviewing this long electrocardiographic record is a cumbersome procedure. A convenient method of recording electrocardiograms and fied ele...
متن کاملImproved Iterative Decoding for Perpendicular Magnetic Recording
An algorithm of improving the performance of iterative decoding on perpendicular magnetic recording is presented. This algorithm follows on the authors’ previous works on the parallel and serial concatenated turbo codes and low-density parity-check codes. The application of this algorithm with signalto-noise ratio mismatch technique shows promising results in the presence of media noise. We als...
متن کاملPatterned medium for heat assisted magnetic recording
Heat assisted magnetic recording HAMR is a potential solution to extend the limits of conventional magnetic recording. In HAMR, the heating of the recording medium is achieved with a near-field optical transducer. Although the literature suggests novel transducers, there is little consideration of the optical and thermal aspects of the magnetic medium. In this letter we suggest a recording medi...
