    摘要： The present invention provides efficient management of calibration and spare sectors on a banded optical write-once, read-many (WORM) disk. A portion of each band on the disk includes a user data area and a reserved area. Sectors in the reserved area are usable either as spare sectors, replacing defective sectors in the user area, or as calibration sectors, for use when the laser write-power level is calibrated. Sectors preferably are used for sparing from one end of the reserved area while sectors are used for calibration from the opposite end. A common overflow reserved area can also be provided for use if all of the sectors in one or more primary reserved areas associated with any of the bands have been exhausted.

    摘要： An optical disk data storage system uses two lasers to write data on the disk, preferably using pulse width modulation (PWM). The lasers direct two independently controllable laser beams to the disk to form two spots that are spaced apart a fixed distance along the data track. Each laser is independently controlled by a modulator that causes the laser to emit the laser beam in a highly pulsed manner. The two laser beams can be simultaneously and independently pulsed along a single track and each beam may be pulsed on any given write clock period and at any of several different power levels. The pulsed lasers write spots of substantially the same size on the disk. The PWM run lengths are recorded on the disk as marks comprising either a single isolated spot or a series of contiguous or overlapping spots. The pulsing of the two lasers is synchronously interleaved so that either adjacent marks (mark-interleaved writing) or adjacent mark edges (edge-interleaved writing) are alternately written by the two lasers. In this manner, an amount of time elapses between the writing of successive marks or mark edges, thereby significantly reducing the effect of thermal buildup by allowing time for the data layer in the optical disk to cool.

    摘要： A unique method for recording, reading and erasing data bits in a data storage device is described. Using extended scanning tunneling microscopy (STM) techniques, a tunneling electron current by resistive heating selectively melts discrete areas of a state-transformable film; then heat is dissipated rapidly, writing data bits by changing the film in said areas from a first state to a second state wherein an electronic property, such as conductance, work function or band gap, in said areas is changed.Again, using extended STM techniques, the effect of this changed electronic property of said film on the tunneling current is measured for reading the written data bits. Minimizing the effect of blemishes on the material is effected, during operation in STM constant current mode by measuring dI/dV or dI/ds, and during operation in STM variable current (constant gap) mode by measuring (dI/dV)/I or (dI/ds)/I.Also by using extended STM techniques, data bits can be selectively erased by resistance heating the film to a temperature higher than the crystallization temperature for a sufficient period of time, restoring selected discrete areas to said first state and each affected electronic property substantially to its original condition.

    摘要： A method of fabricating workpieces includes one or more layers on a substrate that are masked with an ion implantation mask comprising two or more layers. The mask layers include a first mask layer closer to the substrate, and a second mask layer on the first mask layer. The method also comprises ion implanting one or more of the layers on the substrate. Ion implantation may form portions with altered physical properties from the layers under the mask. The portions may form a plurality of non-magnetic regions corresponding to apertures in the mask.

The patterned layer includes plurality of grooves. The stop layer is positioned on the patterned layer. The stop layer is at least partially positioned within the plurality of grooves and a portion of the stop layer may be positioned on walls of the grooves of the patterned layer. The fill layer is at least partially positioned within the grooves between portions of the stop layer. The stop layer substantially separates the fill layer from the patterned layer.
