Latest Patents

Watabe holds a patent for a "Data erasure apparatus and data erasure method." This invention prevents a spindle motor from stopping rotation while data on a magnetic disk is being erased by utilizing a permanent magnet. In one embodiment, the entire area of the magnetic disk is erased as a result of the magnetic disk rotating within the magnetic field of the permanent magnet, which is strategically positioned to face a section of the magnetic disk. Additionally, a back yoke is placed to face a base, providing a magnetic force to the spindle motor that counteracts the magnetic force of the erasing permanent magnet. This design allows the fluid dynamic bearing spindle motor to maintain its rotation without interruption.
