Abstract: An information recording processing apparatus includes a modulating portion operable to modulate write data on an information recording medium and to create code data thereby; and a DC level calculating portion operable to calculate a DC level corresponding to a given run length based on a coefficient defined in accordance with the run length of a component bit of the code data, wherein DC-controlled code data is created or selected based on a DC level addition result based on the DC level corresponding to the given run length, and the created or selected data is defined as write data onto the information recording medium.

Abstract: A surface computer includes an address generator for generating an address for adjusting surface region data concerning at least a storage region and a concurrent computer, provided at a subsequent stage of the address generator, having a plurality of unit computers.

Abstract: A press roll system employed in connection with a web finishing assembly is provided. The press roll system includes a press roll, which cooperates with a head roll to provide a uniform nip area and pressing load; a support substrate, arranged between the ground and the press roll; at least one backup roller mounted to a first surface of the support substrate along a continuous axis for substantially the length of the press roll, and arranged to provide a uniform load to the press roll and uniform area between the press roll and head roll during operation to impart a uniform caliper to the web; and a retractable force actuator, mounted on a second surface of the support substrate, opposite the surface to which the backup rollers are mounted, to provide an even distribution of loads toward the press roll. A channel is attached to one end of the support substrate for receiving and channeling working fluid away from the rest of the press roll system.
