    摘要： A method of using electromagnetic radiation to control exposure of media to electromagnetic radiation is presented. The method includes rotating the media and sensing a frequency of electromagnetic radiation radiating from a rim of the media with a stationary detector. Exposure of the media to electromagnetic radiation with a movable source is controlled with the sensed frequency to provide increased accuracy.

    摘要： One embodiment of an optical medium recording apparatus includes an optical medium support including a support surface, a first light source that projects a first recording light beam focused at a first position relative to the support surface, and a second light source that projects a second recording light beam focused at a second position relative to the support surface, the second position different from the first position, wherein the first recording light beam and the second recording light beam are both projected to the support surface in a single direction.

    摘要： A method of focus control is disclosed. In a passing action, a light source beam is passed over a reflectivity change on a storage media and on to a leading photo sensor and a trailing photo sensor. In a determining action, it is determined whether the leading photo sensor or the trailing photo sensor had a first change in reflectivity. If the leading sensor experienced the first change in reflectivity, then, in an adjusting action, a focus actuator is adjusted to move a focus lens farther from the storage media. If the trailing sensor experienced the first change in reflectivity, then, in another adjusting action, the focus actuator is adjusted to move the focus lens closer to the storage media.

    摘要： A processor-readable medium comprises processor-executable instructions. The instructions are configured for scanning a reference pattern on a disc to determine a first radial position of the laser, wherein the reference pattern is located at a first nominal distance from a center of the disc and extends to a second nominal distance from the center of the disc, wherein the first and second nominal distances are accurate to within a nominal runout tolerance. The instructions are also configured for reading media ID data on the disc only when the radial position is greater than or equal to the first nominal distance plus the nominal runout tolerance and is less than or equal to the second nominal distance minus the nominal runout tolerance.

    摘要： An error correction circuit for determining an error in rotational speed of a recordable disk of a disk drive includes a sinusoidal error calculation portion adapted to generate a true oscillation error signal, and a summation portion adapted to combine the true oscillation error with a spindle error signal to generate a total error signal. The sinusoidal error calculation portion is adapted to generate a new true oscillation error based on the total error signal.
