The present disclosure generally relates to a head assembly of a data storage device. The data storage device may include magnetic media embedded in the device or magnetic media from an insertable cassette or cartridge (e.g., in an LTO drive), where the magnetic head assembly reads from and writes to the magnetic media. During drive operation, the magnetic media moves across the magnetic head assembly. The magnetic head assembly is spaced a distance from the magnetic media such that non-contact recording occurs between the magnetic head assembly and the magnetic media. The magnetic media is supported by either a back plate or an air film generated by one or more fillet edges of the back plate and the velocity of the magnetic media as the magnetic media moves across the magnetic head assembly.
