Latest Patents

Rolf W Hogan holds a patent for a write-read magnetic recording head. This invention features a write magnetic head and a read magnetic head that are closely spaced apart. Each head is equipped with a shield made of a ferrous-containing material, which has an opening where the primary gap is positioned. The design includes a C-shaped core element and an I-shaped core element that define the primary gap. Additionally, a secondary gap is created between the I-shaped core element and the adjacent wall edge downstream of the write gap. When energized, the shields and the secondary flux work together to minimize flux leakages towards the read gap, allowing for effective reading while writing.
