Abstract: A photovoltaic-based fully integrated portable power system includes (1) an integrated power management, storage, and distribution (MSD) subsystem including a case having an opening, (2) a flexible photovoltaic module capable of being disposed in at least a folded position and an unfolded position, where a portion of the flexible photovoltaic module is disposed over the opening of the case, and (3) a mounting plate disposed on the flexible photovoltaic module and over the opening of the case, such that the portion of the flexible photovoltaic module is sandwiched between the MSD subsystem and the mounting plate.

Abstract: A method of and apparatus for burnishing a surface of a magnetic disc of a disc drive are disclosed. The disc drive has a data head and an actuator supporting the head as the head flies above the surface of the disc. A controller causes the disc to be rotated at rates of rotation which will result in burnishing head fly heights which are less than a normal operational fly height of the head. An actuator controller controls the actuator to repeatedly move the head across a region of the disc during a burnishing time period. The head flies above the surface of the disc at the burnishing fly heights during the burnishing time period to thereby reduce asperities on the disc.
