Abstract: The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.

Abstract: An adaptive guard band for a ramp load/unload device is disclosed to provide extended data storage. In illustrated embodiments, an adaptive guard band algorithm is configured to format one or more discs or media having a lower capacity device with the adaptive guard band and extended data zone utilizing capacity measurements. The algorithm formats the media to provide a track zero at a first cylinder if the capacity is at or above the threshold capacity and a second cylinder if the capacity is below the threshold capacity to provide the extended data storage zone. A size or width of the extended data zone is variable to provide additional capacity to meet the threshold capacity.
