ABSTRACT:
A write-read magnetic head for write-read digital recording machines includes a write magnetic head and a read magnetic head disposed in closely spaced apart relation. Each head includes a shield formed of a ferrous containing material having an opening therein in which the primary (write or read) gap is positioned. Each head includes a magnetic core comprised of a C-shaped core element and on I-shaped core element defining the primary (write) gap. A secondary gap is defined between the I-shaped core element and adjacent wall edge downstream of the write gap. When the recording head is energized, the shields and the secondary flux reduces flux leakages towards the read gap to permit effective reading while writing.
