With a total of seven patents to his name, Bronshvatch has developed innovative solutions that enhance the performance and reliability of hard disc drives.

Latest Patents

One of his latest patents is the "Dual member disc clamp for uniform clamping load distribution." This invention involves a disc drive that utilizes a dual disc clamp to secure multiple hard discs. The design features a top circular clamp member and a bottom circular clamp member, both having identical shapes and areas. The bottom member includes holes that minimize disc distortion, while the top member has a concave upper surface and the bottom member has a convex upper surface. The clamp applies pressure through screws, ensuring the discs remain securely in place. Additionally, the spindle motor connected to the dual disc clamp provides a higher torque constant, allowing for reduced start and run current.

Another significant patent is the "Actuator latch activated by head gram load for hard disc drives." This invention presents a latching mechanism for a disc drive actuator that employs a constant force to keep the latch unlatched during operational mode. The actuator's power is utilized to move the latching mechanism into a latched position, either through program control or when power loss is detected. This mechanism ensures that the actuator remains in its park position, even under mechanical shock, until power is restored. The unlatching process is initiated by increasing the spindle motor's speed, which allows the heads to fly and disengage the latch.
