Аннотация:An expression is presented which relates the print-through of a magnetic tape at the optimum recorded wavelength to a constant plus 10 logarithm of (retentivity times coating thickness/base film thickness). The constant is obtained from print-through measurements on several magnetic tapes made with a gamma ferric oxide.
