Zusammenfassung:Embodiments of the invention relate to a hard disk drive (HDD) formatted with at least two surfaces, each of the surfaces serviced a write head, each write head configured for the respective surface. At least one of the surfaces of the HDD is serviced by a random block overwrite (RBO) head for an associated surface. Similarly, at least one of the surfaces of the HDD is serviced by a shingled magnetic recording (SMR) head for an associated SMR surface. The properties of both the RBO and SMR surfaces are retained, and at the same time leveraged to maximize data density and write performance in a single HDD.
