DIY laser turntable plays Morton Subotnick's "Silver Apples of the Moon"

    imagine if this technology was perfected. the fidelity of vinyl without the wear caused by repeated plays using a needle.

    Actually laser turntables have been commercially available since the '90s. They are fairly expensive, but have some advantages.
