A rate 2/3 code for digital magnetic recording is described which results in a sequence where ones (transitions between saturation levels) are separated by at least one (1) but no more than seven (7) bands. The minimum (d) and maximum (K) slots between transitions are d=1, K=7; state (See Original.) , i=0, 1, 2, ...,7 indicates the number of slots since the last transitions, and zeros and ones, respectively, denote the absence and presence of a transition.
