Abstract: An apparatus and a method for processing information, and a program and a program storage medium are disclosed. A content processing routine 152-1 controls the display of a thumbnail and determines whether or not a predetermined time has passed with the thumbnail selected. If the predetermined time is found passed with the thumbnail selected, the content processing routine 152-1 controls the display of the information associated with the thumbnail to a predetermined position corresponding to the display position of the thumbnail.

Abstract: A content processing routine divides a thumbnail-area according to data size and generates the same number of pixels values as the number of divided thumbnail-areas.

Abstract: A magnetic or optical disk apparatus having a flexible disk rotated at high speed and head sliders for reading and writing information on the disk, floating from both sides of the disk. The disk apparatus is also provided with straightening plates for keeping air flow in the radial direction of the disk as a laminar flow to surely prevent the disk from being vibrated at the time when the disk is rotated at high speed. As the result, positions of the head sliders relative to the disk can be surely and accurately maintained to provide heads with excellent recording and reproducing characteristics. Mass storage and high speed access can be thus achieved without damaging the flexible disk and the disk apparatus can be smaller-sized with lighter weight and lower cost.

The laser frequency can be offset from the frequency of the absorption line, and also the offset frequency can be varied continuously.
