Patent ID: 7848212

Claim:
A high-density optical data storage apparatus having a reading/recording head comprising; an input fiber-optical (FO) line optically connected to an input fiber-optical (FO) collimator; an output fiber-optical (FO) line optically connected to an output fiber-optical (FO) focuser; a prism or mirror with semi-transparent coating; an one-dimensional acousto-optical cell; an input/output focusing lens; and a diaphragm; wherein said input FO line transmits an optical signal coming from a remote fiber-optical (FO) laser of said high-density optical data storage apparatus to said reading/recording head; wherein, said optical signal coming from said input FO line is collimated by said input FO collimator, reflected from said prism or mirror with semi-transparent coating, and enters said acousto-optical cell which deflects said optical signal precisely positioning a light spot developed by said input/output focusing lens on a working surface of an optical disk; a light signal reflected backward from said working surface of said optical disk is collimated by said input/output focusing lens, passes backward through said acousto-optical cell, passes through said prism or mirror with semi-transparent coating, and is finally inserted, by said output FO focuser, into said output FO line; wherein said reading/recording head is mounted on a conventional radial moving mechanism.
