Read Channel Modeling for Detection in Two-Dimensional Magnetic Recording Systems
Anantha Raman Krishnan, Rathnakumar Radhakrishnan, Bane V. Vasic · IEEE Transactions on Magnetics · 2009
In this paper, we describe a read channel model for detector design for two-dimensional magnetic recording (TDMR) system, a novel strategy for recording at upto 10 Tb/in2. We describe a scheme for (1) modeling of the recording medium, (2) modeling of the write/readback process, and (3) an experimental method for the characterization of noise in the TDMR channel, occurring due to irregularities in the bit-boundaries in the recording medium, that can be used for detection purposes.
