%X In measurements of time decay in a perpendicular double\|layered medium,a large output decay was observed when a regular single\|pole head was used for both writing and reading.Investigations of this phenomenon revealed that the demagnetization of the medium was caused by the instability of the domain wall of the main pole film and also by the concentration of strayfields by the main pole during the reading process.Several countermeasures were proposed.
