Test tapes
For reproduce alignment: Fostex P/N 82660100
or - ° [MRL 21J1O3, Magnetic Reference Lab.]
All specs are identical with 82660100 except for
the reference fluxivity which is 200nWb/m and
thus its reproduce output level will be 2dB lower.
° [BASF Calibration Tape (DIN 45513/2)]
All specs are identical with 82660100 except for
the reference fluxivity which is 320nWb/m and
thus its reproduce output level will be 1.5dB higher.
For wow/flutter measurement: Fostex P/N 82260080
or - 0 [STL #53-1, Standard Tape Lab.]
