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： An semiconductor integrated circuit that uses a low-frequency operation clock to implement probing for fast operation. This semiconductor integrated circuit comprises a time adjustment circuit for adjusting the pulse width of enable signals. In normal mode, the time adjustment circuit does not convert the pulse width of enable signals. However, during probing, the time adjustment circuit converts an enable signal into an enable signal with a short pulse width for testing. In normal mode, a memory control circuit operates to synchronize with an unconverted enable signal. During probing, it operates in synchronization with an enable signal converted to one with a shorter pulse width.

摘要： A video/computer game machine maps external images onto animated game players in a game program. An image of a person's face may be mapped onto the head of an animated game player. The person may then play the game using the animated game player having a face that appears to be that of the person. Similarly, images of other persons can be mapped on other animated game players that appear in the video game program. Improved realism of video games is obtained by enabling individuals to create animated game players that have features, e.g., a facial image, of the individual or that were selected and imported by the individual.

摘要： In a recording method for a rewritable optical recording medium, immediately before a prospective leading pulse that is a time section where recording light of write power Pw irradiates a phase-change recording layer for the first time as a front low-power energy irradiating step, light of bias power Pb irradiates the phase-change recording layer for a first set time length yT as a preceding low-power energy irradiation step. And immediately after the leading pulse, the light of bias power Pb irradiates the phase-change recording layer for a set time length xT as a succeeding low-power energy irradiation step. The relation between x and y satisfies: 0.95≦x+0.7*y≦2.5. The high-power energy beam irradiates the recording medium in such a manner that a period of irradiation for pulses subsequent to the leading pulse is in a range of from 0.5T to 2.5T. The result is that it is possible to facilitate forming/erasing amorphous marks even in a phase-change recording medium devoid of a reflective layer, without any risk of narrowing the range of effective crystallization speeds.
