Abstract
A new technique for distinguishing partial erasure from nonlinear transition shift (NLTS) is presented for the case of a dibit. Experimental results obtained by using the method show that the partial erasure of a square wave is twice as large as that of a dibit. Calculation of NLTS using a first-order approximation is not correct at high recording densities
