Recordable disc and motor

A device comprising:

• a recordable disc, the recordable disc including:
• a recordable surface, and
• at least two magnetic components;
• a substrate adjacent to the recordable disc;
• and
• at least two coils fixed to the substrate, wherein electrical current in the coils is adjusted to provide electromagnetic forces on the magnetic components to rotate the recordable disc.

A storage media comprising:

• a substrate;
• a recordable layer adjacent the substrate;
• and
• a shield layer between the substrate and recordable layer, wherein the shield layer insulates the recordable layer from electromagnetic fields.

A device comprising:

• a recordable disc, the recordable disc including:
• a recordable surface, and
• at least two conductive plates;
• a substrate adjacent to the recordable disc;
• and
• at least two electrodes fixed to the substrate, wherein voltage applied to the electrodes is adjusted to provide electrostatic forces on the conductive plates to rotate the recordable disc.
