>The Laser Turntable uses five laser beams to play records, Two of them
>read the audio signals from the right and left channels.  Two more keep
>the beams in their respective channels, and one final one controls the
>distance from the record. This is part of the reason the Laser Turntable
>is successful at playing broken, cracked, records up to 1/4 quarter of an
>inch (5-6mm).
>
>The Laser Turntable eliminates most noise from scratches because it doesnt
>read information  at right angles to the  groove.  
>
>Records are engraved from the shoulder to bottom of the groove. When the
>Laser reads a record, it  uses the upper portion  of the groove. The laser
>beam can be adjusted up and down  the top 10 microns to find the least
>wear and best signal.  Also, the incident area of the laser beam is only a
>fourth of the contact  area of a high end stereo needle and is twenty-six
>times smaller than that of a mono needle.
>
>There is currently two models of the Laser Turntable: The LT-1LA steps
>through its 30 rpm to 50 rpm range at 0.1 rpm increments.  The LT-XA adds
>the range of 60 rpm to 90rpm at increments of 0.2 rpm

>HISTORY:
>
>( Excerpted from www.elpj.com/era.html)
>                         
>When Robert E. Stoddard, a young American engineer, proposed his theory
>that records could be played with light, his friends and teachers at
>Stanford University doubted him .
>
>   After graduation, he established Finial Technology Inc. for the purpose
>of developing his idea. Over a  period of seven years, with financial
>backing (about twenty million dollars US) from people who shared  his
>vision, he developed the basic technology to fulfill his dream. His is an
>example of the American   pioneering spirit celebrated throughout the
>world.
>
>   Stoddard came to Japan in 1988 to seek business partners, but all the
>Japanese audio equipment   manufacturers rejected his offer. The reasons
>were that the record market was on the decline and that
>  the laser turntable did not lend itself to mass production.
>
>What the manufacturers were used to was adopting a standard design for
>hardware and software that  could be turned over to a production line
>reducing the price per copy as the copies increase. The laser  turntable,
>on the other hand, called for hardware used for no other application than
>reading records.  Therefore the heart of the laser turntable would have to
>consist of tailor-made, hand-crafted parts with their necessary production
>costs.
>                                                           
>
>  To this end ELP, a Japanese company, acquired the technology from
>Stoddard to further the   development of the Laser Turntable. Over a
>five-year period ELP undertook a complete review of the electronic
>circuitry and optical components, created new functions and developed a
>hand-assembly  operation. The excellence of the new Laser Turntable is the
>result of this painstaking process.
