ABSTRACT:
A read/write head in a recording and retrieval system and method of operating the read/write head are disclosed. The read/write head contains two inductive sections coupled to a switch. During a read operation, the switch is open connecting the sections in series and maximizing the inductance of the read/write head to produce a better read operation. During a write operation the switch is closed connecting the sections are in parallel to reduce the inductance of the read/write head to produce a better write operation. The switch is controlled by the R/W.sub.-- signal of the recording and retrieval system. The inductance of the inductive sections can be modified to optimize the read and write operations.
