Latest Patents

Se-Tae Kim holds a patent for a "Method and apparatus for controlling revolution speed of spindle motor in optical disk drive." This invention focuses on a method of controlling the revolution speed of a spindle motor in an optical disk drive. The process involves calculating target RPMs and actual PWM signal values necessary for maintaining these RPMs based on the recording linear velocities of an optical disk. These values are stored in memory, allowing for precise control of the spindle motor. The motor is initially controlled by a PWM signal value that exceeds the actual PWM signal value until the desired target RPM is achieved. Once the spindle motor reaches the target RPM, it is then controlled by the actual PWM signal value.
