Masahiro Kanamaru is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic disk technology, holding a total of 5 patents. His work focuses on improving data recording methods and enhancing the performance of magnetic disk apparatuses.

Latest Patents

One of Kanamaru's latest patents is a magnetic disk apparatus and data recording method. This invention involves a magnetic disk apparatus that stores read position dependency information on the read signal quality of a data region at a first track. It measures the read signal quality at a predetermined radial position in a second data region of a second track, which is different from the first track. The positioning error of the second data region is determined based on the read position dependency information and the read signal quality at the predetermined radial position. This method ensures that data recorded in a target data region does not overwrite data in an adjacent second data region by utilizing the determined positioning error.

Another notable patent is related to a controller, disk drive, and read processing method. In this embodiment, an equalizer is designed to obtain noise included in a first correction signal by using noise components from both the first and second tracks. The equalizer corrects the first correction signal using the obtained noise and equalizes it. The noise components are calculated based on measurements taken at different timings, allowing for more accurate decoding of the equalized first correction signal.
