007/10 Sound recording (/00 = s) |
Kind of material (Variable Control Field - Physical Description Fixed Field) |
Character position definition and scope:
A one-character alphabetic code indicates the kind of material used in the manufacture of sound recordings (both instantaneous and mass-produced). This code is only intended to relate to a sound recording rendered on a mechanical device.
Most contemporary commercial or mass-produced 16, 33-1/3, and 45 rpm discs are made of vinyl (plastic). Early discs were made of wax, aluminum, acetate, or shellac. Most commercial or mass-produced 78 rpm discs are made of shellac. Most instantaneous cylinders were made of wax. Compact audio discs (CDs) are made of polycarbonates coated with a reflective surface (usually aluminum).
A fill character ( | ) is used when no attempt has been made to code this position.
Record requirements for National-level and Minimal-level records: Optional.
