Method for recording and reproducing information.

摘要

Material easily vaporized by electron beams are regularly arranged longitudinally and laterally in the form of fine grains on a substrate. An array of the fine grains is scanned by electron beam to turn ON and OFF the electron beam in accordance with signals, thereby selectively vaporizing the fine grains.
<??>The substrate on which information is recorded is scanned by electron beam to detect the presence or absence of the fine grains thereby reading information.
<??>According to this system, recording density of approximately 10<1><2> bits/cm<2> can be realized.
