Disclosed are various systems, methods, and programs embodied in a computer readable medium for calibration of a lens position in an optical disc drive. In one embodiment, a method is provided that comprises manipulating a lens focus actuator to relocate the lens from a first position to a second position. The lens substantially focuses a laser onto the surface of the optical disc when in the second position. The method also comprises determining a first input setting delta to the lens focus actuator that corresponds to a predefined position offset of the lens. The first input setting delta is determined based upon a second input setting delta corresponding to a distance between the first position and the second position.

A memory structure includes a memory storage element electrically coupled to a control element. The control element comprises a tunnel-junction device. The memory storage element may also comprise a tunnel-junction device. Methods for fusing a tunnel-junction device of a memory storage element without fusing a tunnel-junction device of an associated control element are disclosed. The memory storage element may have an effective cross-sectional area that is greater than an effective cross-sectional area of the control element. A reference element comprising a tunnel-junction device may be used with a current source to fuse a memory storage element without fusing a tunnel-junction device of an associated control element. Methods of making the memory structure and using it in electronic devices are disclosed.

A method of mapping a surface of a printable medium comprises illuminating the surface with electromagnetic radiation and focusing the electromagnetic radiation with a focusing means. The method also includes modulating the position of the focusing means using an actuator, wherein the actuator has a resonant frequency. An input signal is provided to the actuator, wherein the input signal comprises an AC waveform having a frequency. The frequency does not correspond to the resonant frequency of the actuator. The waveform does not have higher harmonics corresponding to the resonant frequency of the actuator.

An optical pickup unit (OPU) includes a moveable structure that is moved by a voice coil motor component in response to an input signal. The moveable structure includes a pattern that is moved corresponding to the input signal. An encoder reads the pattern to generate an output signal that corresponds to pattern movement as the input signal is applied over a period of time. A controller calculates a calibration factor relating the pattern movement to the input signal.
