Learning Event 1:
DESCRIBE AUDIOTAPE
1.
Magnetic tape characteristics. All magnetic tapes consist of a coating, or emulsion, permanently
bonded to a plastic base. The coating contains microscopic oxide particles that can be magnetized by
the electromagnetic recording head. The base film, which determines the mechanical properties of the
tape, is the physical support for the coating. Holding the particles to the base material is a binder
composed of a highly complex blend of resins and plasticizers. It binds all the oxide particles together
into a strong but flexible coating and plastic base.
a. In most cases, it is easy to distinguish the shiny base side from the dull coated side of the
tape. However, some tapes, particularly cassettes, have a polished coating that is nearly as shiny as the
base.
b. Open reel tapes are always wound with the coated sides facing the hub. In cassette and
cartridges, the coating faces out because of the tape path arrangements.
2.
Tape qualities. There are three main qualities that magnetic tape should possess:
a. Permeability. The ability of a material to attract a magnetic force.
