Latest Patents

One of Lee's latest patents is a flying head positioner that features rotational fine positioning and adjustability. This flying head mechanism includes a flying head, a suspension, and an actuator that applies a load force through the suspension. The load force can be adjusted while the head is in operation, allowing for active control as part of a feedback loop that maintains a constant flying height. In one embodiment, a voice coil actuator is utilized. Additionally, when using an optical flying head, a conventional focus sensor provides a signal indicative of flying height, which helps in correcting any flying height errors. The flying head is equipped with a contact sensor to detect head/disk contact and includes means for changing the focus of the optical elements without altering the flying height. The entire suspension is designed to be immune to shock and vibration. In some embodiments, two heads may be employed to read or write more than one type of media.

Another notable patent involves a phase change optical medium that is compatible with a flying head. This medium consists of a substrate, a reflective layer, a first dielectric layer, a phase change information carrying layer, a second dielectric layer, and a lubricant layer. The materials and structure used in this invention protect the phase change layer from mechanical damage and heat generated by impacts.
