Using a disposable magnetographic master tape eliminates the problem of toner contamination at the write station and thus facilitates high resolution magnetic printing with either an array head or a scanned head. The write processes in both magnetic printing and magnetic recording are very similar, and track recording densities in excess of 2000 per inch have been routinely achieved in the latter. However, this high resolution potential has not been achieved in magnetic printing because the requirements for writing high resolution latent images and toning them in the same environment are not compatible.
