It is necessary in magndc tape units to write information on tape and verify it by reading with a read head a shoa time later. This means that the read head may receive a flux component from the write head which is of siguifkaut magnitude compared with the signal flux it is detecting from the tape and this is especially true if the write head and read head are close together-an essential design-aim if the" dead" tape at the endof a recorded block of information (the inter-block gap) is to he minimised. The MSCA 3-D Package was used to study the electro-magnetic behaviour in Read-While-Write heads. Analytical and numerical methods of calculating magnetic flux distributions and other problems can often he4 a head designer understand how the flux spreads and therefore how the head size for a given ovd conlipation is limited. To verify these simulation results, measurements with MEUinductive head were done.
