ABSTRACT:
Magnetic transducer-keeper combination embodiments of the invention are described. Each has a magnetic core defining a physical gap and a thin magnetic keeper arranged in close proximity of the core to bridge the gap. A magnetic flux from the gap saturates the keeper inan area bridging the gap, thereby forming a signal transducing zone in the keeper. The keeper is maintained stationary and the core moved or scanned with respect to the same, thereby moving or scanning the transducing zone in the keeper.
