  Abstract

The requirement for high-density data storage systems has increased due to the explosion in data growth. Bit-patterned media recording (BPMR) is a candidate for the next-generation magnetic recording systems, and its many advantages facilitate the achievement of recording densities of 1 Tb/in² and beyond. In BPMR, each information bit is represented by a magnetic island; however, due to the small spacings between the along- and across-track islands that are for the achievement of a high areal density, severe extents of the intersymbol interference and intertrack interference (ITI) appear. These error factors degrade the system performance of the recording system. In this paper, we verify the performance of 8/10 modulation code according to areal densities on BPMR. When areal density is 1.5 Tb/in², the random data exhibited performance gains of ～0.2 ㏈ over a modulation code at a bit error ratio of 10-4. However, when areal density is 3.0 Tb/in², the modulation code exhibited performance gains of ～1 ㏈ over a random data at a bit error ratio of 10-4.
