Constructive inter-track interference (CITI) codes for perpendicular magnetic recording
Journal of Magnetism and Magnetic Materials, 2005This paper presents new modulation codes to reduce the effect of adjacent track interference (ATI) also known as inter-track interference (ITI). New modulation codes, that is constructive inter-track interference (CITI) codes and partial response (PR) targets, are investigated using computer simulation in perpendicular magnetic channel. CITI codes have

Generalized Interlaced Magnetic Recording With Flexible Inter-Track Interference Cancellation
IEEE Transactions on Magnetics, 2018In this paper, interlaced magnetic recording (IMR) is generalized with a flexible inter-track interference cancellation (F-ITIC) scheme to enhance the overall areal density capability (ADC) by balancing and mitigating the mutual ITI between neighboring tracks.

Inter-track interference cancelation in presence of frequency offset for shingled magnetic recording
2013 IEEE International Conference on Communications (ICC), 2013The enormous growth of consumer electronic industry is driving the need for achieving ultra-high areal storage densities. Shingled magnetic recording (SMR) is a promising high density storage technique where shingles are created by overlapping tracks for increasing the track per inch (TPI) and achieving higher areal densities. High TPI values, however,

Asynchronous Inter-Track Interference Cancellation (A-ITIC) for Interlaced Magnetic Recording (IMR)
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017In this study, a novel inter-track interference (ITI) cancelling scheme is proposed for the interlaced magnetic recording (IMR). Recently proposed IMR shows an areal density capability (ADC) gain by recording tracks in an interlaced manner with separately optimized linear densities, while the severe ITI at the double-sided squeezed tracks limits the ...

Two-dimensional coding for a multi-track recording system to combat inter-track interference
IEEE Transactions on Magnetics, 1998Increasing track density, through a narrowing of the read head, leads to a reduced signal-to-noise ratio and increased inter-track-interference (ITI). Two-dimensional codes for multi-track recording systems have demonstrated increased capacity over conventional single track run length limited (RLL) codes. This paper describes a two-dimensional code for

Flexible Inter-Track Interference Cancellation for Generalized Interlaced Magnetic Recording
2018 IEEE International Magnetics Conference (INTERMAG), 2018Interlaced magnetic recording (IMR) shows potential to achieve higher areal density capability (ADC) than conventional magnetic recording by recording tracks in an interlaced manner [1]. Top and bottom tracks can be recorded in different frequencies such that the bit error rate (BER) performance can be balanced, providing extra track or linear density ...

The readback signal of patterned media storage (PMS) is corrupted by a two-dimensional interference consisting of inter-symbol interference (ISI) and inter-track interference (ITI). In this paper, we apply the turbo equalization to mitigate the ITI effects. The codeword of the outer code is divided and then written on three separate tracks.

In this paper, an adaptive inter-track interference (ITI) mitigating scheme is proposed for interlaced magnetic recording (IMR) with random frequency offsets. Recently, proposed IMR has a potential areal density capability gain over conventional perpendicular magnetic recording, as it involves writing tracks with differentiated linear densities in an ...

Inter-track interference studies using MFM image reconstruction
IEEE Transactions on Magnetics, 1997The Magnetic Force Microscopy (MFM) image reconstruction technique has overcome difficulties in interpreting MFM images of data tracks written on longitudinal recording media. In this work, MFM image reconstruction is used to study the vector magnetization components of closely spaced tracks.
