Abstract: Before a host computer transmits image forming data to a CD-R drive, the CD-R drive transmits information of an image forming condition preset in the CD-R drive to the computer. The host computer generates, based on stored original image data, image forming data adapted to the image forming condition on the basis of the information of the image forming condition and transmits the generated image forming data to the CD-R drive. The CD-R drive forms a visual image according to the preset image forming condition on the basis of the transmitted image forming data.

Abstract: When an optical disk image forming device forms an image on an optical disk, the image forming device reads information of kinds of coloring matters used in an image forming area from information described in an information area of the optical disk. Then, the optical disk image forming device reads from a table laser power strength information corresponding to the information of the kinds of the coloring matters and a maximum linear velocity (Nx) at the time of forming the image and applies a laser beam having this laser power strength to form the image on the image forming area of the optical disk. Thus, since the discoloration of the coloring matter in the image forming area is always saturated, the image having a constant contrast can be formed on the image forming area of the optical disk.

Abstract: A drawing pulse generating unit of an optical disk recording apparatus judges a bit stream of main data contained in a bit stream signal of frame-formatted data, and generates pulse signals DOTX 1 and DOTX 2 based upon the judgment, and then, outputs the generated pulse signals DOTX 1 and DOTX 2 to the gate circuit. In a time period during which a signal level of the pulse signal DOTX 1 is an “H” level, the gate circuit supplies a bit stream signal of the frame-formatted data to a laser driver. In a time period during which a signal level of the pulse signal DOTX 1 is an “L” level, the gate circuit supplies a bit stream signal indicative of an erase level to the laser driver. The laser driver controls an optical pickup so that a laser light having strength indicative of the bit stream signal is irradiated.

Abstract: An LPF performs low-pass filtering for a light reception signal responsive to return light received by an optical pickup. A comparator makes a comparison between the level of the signal output from the LPF and a predetermined threshold value and outputs a high or low pulse signal MIR. A system control section determines the pulse signal MIR for each predetermined dot region. If the pulse signal MIR output from the comparator is high, the system control section writes “1” into buffer memory; if the pulse signal MIR is low, the system control section writes “0”into the buffer memory. The pixel string data recorded in the buffer memory is transferred to a host and an image responsive to pixel string data is displayed on a display.

Abstract: A data recording layer and an image drawing layer are disposed in an optical disk. Optical pickups are disposed on opposite sides of this optical disk, respectively. One of the optical pickups records data on the data recording layer. The other optical pickup forms a visible image on the image drawing layer. The one of the optical pickups detects a predetermined rotation reference position from the optical disk before an image drawing operation on the image drawing layer by the other optical pickup. An orientation of the visible image is set on the basis of the detected rotation reference position to form the visible image on the image drawing layer.

Abstract: An optical disk is equipped with a predetermined mark. A frequency generator outputs an FG pulse of frequency corresponding to the rotational speed of a spindle motor used for rotationally driving the optical disk. The edge of the FG pulse detected by an edge detection section is counted by an FG counter. An angle counter measures the duration of a time from appearance of an edge of the FG pulse until a point in time when the mark affixed to the optical disk 1 is detected. A count value of the FG counter, which has been acquired at the point in time when the mark is detected, and a count value of the angle counter are saved. In a case where a visible image is rendered, encoding of a visible image to be rendered is started when the count value of the FG counter and the count value of the angle counter have become equal to the respective saved values.
