ABSTRACT:
Systems and techniques relating to writing servo information on a machine-readable medium. A method of performing post-assembly operations in a recording apparatus, including a rotating recording medium, includes writing sloped tracks to the recording medium using a calibrated current profile, and writing servo information to the recording medium using the sloped tracks. An apparatus can include an input; an output; and signal processing circuitry coupled with the input and the output to control a transducer to write to a rotating recording medium, the signal processing circuitry including one or more control units configured to cause performance of post-assembly operations including writing sloped tracks to the recording medium using a calibrated current profile, and writing servo information to the recording medium using the sloped tracks.
