摘要： The object is to enable suppression of an excessive number of changes in assignment of a server in charge of communication in response to movement of a terminal. A position-information acquisition unit in a computer acquires information on the position of a mobile terminal as a candidate for a destination of information provision. Then, a zone determination unit determines whether or not the mobile terminal is in a coverage zone or a margin zone on the basis of the information on the position. An information provision unit starts the information provision to the mobile terminal when the mobile terminal enters the coverage zone, and ends the information provision to the mobile terminal when the mobile terminal goes out of the margin zone.

摘要： In a rewritable compact disc having a wobble groove on a substrate, crystal and amorphous states of a phase-change recording layer are an unrecorded/erased state and a recorded state, respectively. When the recording layer is exposed to recording light, amorphous marks assuming the recorded state are formed. At any of 2-, 4- and 8-times velocities with respect to a reference velocity (1-times velocity) whose linear velocity is 1.2-1.4 m/s, modulation m11 of a recorded signal when the recording light of approximately 780 nm in wavelength irradiates the recording layer via an optical system with NA=0.5 or 0.55 is 60-80%. A topmost level Rtop of reflectivity of the eye pattern of the recorded signal during retrieving at the 1-times velocity is 15-25%, and a jitter of the individual length of marks and inter-mark spaces during retrieving at 1-times velocity is 35 ns or less. Recording at 8-times or higher velocities is thereby realized without any risk of impairing the read-compatibility with the conventional CD-RW specifications at least at 4-times velocity.

摘要： A multilevel recording method based on a principle utilizing a phase change medium. The method radiates a recording energy beam against an information recording medium having a recording layer to locally melt the recording layer. The recording layer is adapted to produce a phase change between a crystalline state and an amorphous state upon being radiated with an energy beam. An amorphous mark is formed by cooling during a solidifying process to record information in the medium. The size of the amorphous mark is controlled mainly by a competition between a recrystallization process and an amorphization process during the solidifying process. An intensity of reflected light from a reproducing light beam radiated region is controlled in three or more multiple recording levels according to an optical characteristic difference between a crystalline region and an amorphous region and their areas.
