Claims64
A phonorecord for embodying an audio recording comprising:
- a. a metal substrate;
- b. a lacquer coating disposed on at least a portion of the metal substrate, the lacquer coating comprising one or more grooves embodying the audio recording;
- and
- c. a conformal coating disposed on at least a portion of the lacquer coating.
A method for producing a phonorecord for embodying an audio recording comprising:
- a. providing a metal substrate;
- b. disposing a lacquer coating onto at least a portion of the metal substrate;
- c. introducing one or more grooves into the lacquer coating, the one or more grooves embodying the audio recording;
- and
- d. disposing a conformal coating onto at least a portion of the lacquer coating.
A phonorecord for embodying an audio recording comprising:
- a. a vinyl substrate, the vinyl substrate comprising one or more grooves embodying the audio recording;
- and
- b. a conformal coating disposed on at least a portion of the vinyl substrate, the conformal coating having a Vickers Hardness of at least about 1000.
A phonorecord for embodying a negative of an audio recording comprising:
- a. a metal substrate, the metal substrate comprising one or more ridges embodying the negative of the audio recording;
- and
- b. a conformal coating disposed on at least a portion of the substrate, the conformal coating having a Vickers Hardness of at least about 1000.
A stylus for playing back an audio recording embodied on a phonorecord comprising:
- a. a carbon-based substrate;
- and
- b. a conformal coating disposed onto at least a portion of the carbon-based substrate, the conformal coating having a Vickers Hardness of at least about 1000,
- c. wherein the stylus is shaped to interface with one or more grooves of the phonorecord.
