Gap Length Losses in Tape Playback

  • John M. Eargle

Abstract

At short wavelengths, the finite size of the playback gap dimension in the direction of tape motion influences the output. This loss is given by the following equation:
$$Response (dB) = 20\log \left[ {\frac{{\sin [1.11\pi (g/\lambda )]}}{{\left[ {1.11\pi \left( {g/\lambda } \right)} \right]}}} \right] $$
(167.1)
where g is the gap length and λ is the recorded wavelength, both expressed in the same units. (The sine term in the numerator must be evaluated in radians.)
