ABSTRACT:
A recording/reproducing system for multiple users is disclosed which includes a plurality of channels connected to multiple users, a data processing portion for processing a signal of input/output information of an optical disk, and an optical head portion for reading and writing the information of optical disk. The optical head portion has at least one ultra-slim, subminiature multi-head device commonly having at least two optical heads, thereby allowing individuals to process desired information at any time.
