ABSTRACT:
A mass data storage arrangement such as for books, is provided, by recording the data in the form of one micron pits in radial rows within spiral grooves of a disc. A reading element comprises a CRT providing a light beam output, which is focused down to one micron in size. The spot output of the CRT is scanned across each row having the presence or absence of pits. The light reflected from the disc is modulated by the presence or absence of pits and is reflected to a photomultiplier. The output of the photomultiplier is decoded and then displayed in human language form.
