Abstract: Embodiments of the present invention provide for apparatus and methods for performing unload operations, including enabling read/write heads to reach a desired velocity at the ramp. Embodiments of the present invention are particularly beneficial for handheld products where low power consumption and reliability are important requirements.

Abstract: A method for generating a velocity command for an actuator assembly is provided. The actuator assembly includes an actuator arm, which is to move over a plurality of surfaces. The method begins by providing a compensation torque for each of the plurality of surfaces. A position of the actuator arm is determined so that it may be mapped to one of the plurality of surfaces, which is the present surface over which the actuator arm is moving. A target velocity is then provided for the actuator arm and input to a controller, which generates a velocity command from the target velocity and a selected compensation torque, which is the compensation torque of the present surface.

Abstract: A method for enhancing music signal fidelity derived from a compact disk storage media comprises exposing the encoded surface of the compact disk music storage media to a series of color fields in sequence immediately prior to playing the compact disk. Preferably the color fields correspond to light wavelength bands: 580-610 nm; 610-660 nm; 540-580 nm; 460-660 nm; and 450-460 nm, respectively.
