Latest Patents

Kikawada holds a patent for a "Data recording and reproducing apparatus using two orthogonal code." This invention involves a data recording device, such as a hard disk apparatus, which features an orthogonal coding circuit and a modulation circuit. The orthogonal coding circuit encodes recording data to be recorded on adjacent two tracks as two orthogonal code streams included in a Hadamard matrix. The modulation circuit outputs recording signals, which are obtained by modulating the code streams using the NRZI system, to a magnetic head. The reproduction signals read out from a magnetic disk by the magnetic head are decoded as recording data based on given decoding rules according to the two code streams. This patent showcases Kikawada's expertise in enhancing data storage and retrieval processes.
