Latest Patents

Sobukawa's latest patents include a disk drive device that features a movable guide for receiving a caddy. This guide operates in the loading and unloading directions on a main chassis. The innovative design allows the movable guide to be shifted by a drive mechanism from an eject position to a disk drive position. The arrangement ensures that when the movable guide is at the eject position, a turntable of a traverse unit is spaced from a disk. As the guide moves in the loading direction, it gradually approaches the disk, allowing for a smooth attraction of the turntable to the disk. Another patent focuses on a pickup device for a disk drive, which utilizes a first and second adjusting base made of leaf spring material. This design allows for slight pivoting and adjustment of the optical axis of a pickup head, preventing shaking and absorbing shock, thus making the device compact and lightweight.
