Test Notes:
1. Thickness measurements are made on Standard Gage Company Inc. Smart Box.
2. Retentivity and Coercivity characteristics are those intrinsic magnetic oxide properties which are dependent upon the nature of the oxide formulation.
Retentivity is a measure of magnetic efficiency, which is the magnetic strength retained in the tape oxide just after the magnetic field is removed.
Coercivity of a magnetic tape is a measure of the magnetizing field necessary to reduce the remnant field to zero. All coercivity and retentivity
values are obtained from a 60 Hz B-H loop tracer with a 3500 Oersted field.
3. Erasure values are obtained by employing a 60 Hz alternating field applied to the tape under test,
which causes a reduction of at least 60 dB to the recorded signal. All test conditions performed
with optimum bias and record level adjusted to the standard record level.
4. RF output is the output of the tape as compared to the standard reference tape.
5. Uniformity is the allowable change in output of a recorded signal measured over the entire
length of the tape.
6. Resistivity is the surface electrical resistance of the coating.
* Average BER of the batch sample tested.
