Two-Dimensional 15/24 Non-Isolated Patterned Modulation Codes With Minimum Hamming Distance 3 in Bit-Patterned Media Recording

IEEE Access
Reducing the distance between magnetic islands is essential for increasing the areal density in bit-patterned media recording (BPMR). Consequently, significant two-dimensional (2D) interference emerges, encompassing inter-symbol interference (ISI) and ...

Multilayer perceptron-based array reader optimization for ultra-high density magnetic recording

AIP Advances
We have previously presented a utilization of a long-short-term memory (LSTM) network to improve the reliability of the log-likelihood ratios (LLRs) in a coded three-head/three-track bit-patterned magnetic recording (BPMR) system. To continuously enhance
