Latest Patents
Raastad holds a patent for a "Fully integrated matrix magnetic recording head with independent control." This invention features a matrix array of recording heads, where each head operates independently in terms of its magnetic circuit and excitation conductors. Each head is designed with a planar magnetic circuit and a helical coil wrapped around its lower part. The matrix array is fabricated using full thin film technology on non-magnetic substrates. The heads are aligned in an oblique lattice, optimizing the write gaps along rows and offsetting them by a constant value along columns. This design allows for independent control of write parameters through interconnects to the backside of the wafer. The die forming the device is shaped to enhance head/medium positioning and minimize wear.
