|Abstract ||:||Shingled perpendicular magnetic recording is one of the candidates for achieving areal recording densities of 1 terabit per square inch and above in next generation magnetic recording. It is assumed that shingled recording would not require a big change in head and media design. Shingled recording uses a write head with wide pole and an extended conventional continuous recording medium. Written tracks partially overwrite adjacent data with a certain track pitch. With the help of the wide pole tip, the write head can generate a large recording field, which resolves the so-called trilemma. The down-side of shingled recording is that a new architecture should be introduced to ensure random access, which is mandatory in hard disk drives. In this article, head and media simulations of shingled recording are surveyed. Experimental results and the issues to be solved are also reviewed.|
