N2 - Composite media, with recording layers consisting of magnetically hard and soft layers were compared with conventional, single layer media using simulations. The difference in the angular variation of switching fields, while large at low temperatures, was much reduced at room temperature. Tracks recorded on composite media can have higher signal-to-noise ratio and/or higher thermal stability than those written on single layer media. Intergranular exchange coupling narrowed the difference between the two media.
