Abstract: PURPOSE: An MCG(Multimedia Compact Graphic) data file generating and reproducing method is provided to include necessary data only for displaying graphics in a generated file, and to optionally designate a data processing speed per second, thereby compressing a space while designating a desired screen size and desired resolution. CONSTITUTION: A system retrieves graphic data from a subcode channel of a disk to extract the retrieved graphic data, and retrieves/extracts audio data from a main channel(210). The extracted data is stored in a temporary memory. The system integrates the graphic data with the audio data, and generates one image file(230). The system extracts the graphic data only from the generated image file, and converts it into an MCG data format file(250). The system separately compresses an audio file only of the image file, and generates an MP3 format audio file(270).

Abstract: PURPOSE: A noiseless blower is provided to prevent noise from being generated from a blower and to simplify a structure of the blower by periodically exhaust air through an air exhaust hole. CONSTITUTION: A noiseless blower includes a blower body(100), a yoke(200), a magnet(300), an air generator, an intake valve, and an exhaust valve(600). The blower body(100) has an air exhaust port(120) and an air intake port. The yoke(200) is installed at a center of an inner wall of the blower body(100). The magnet(300) is installed in the yoke(200). The air generator has a coil(430) movable through a gap formed between the magnet(300) and the yoke(200). The intake valve sucks air through the air intake port and the exhaust valve(600) exhausts air through the air exhaust port(120).
