BIDIRECTIONAL SINUSOIDAL SCANNING SYSTEM |
摘要 |
In a preferred embodiment, the invention relates to systems and methods for storing digital video information on an optical recording medium comprising the steps of moving the optical recording medium in a first direction, sinusoidally scanning a beam of light over the moving optical recording medium in a second direction substantially perpendicular to the first direction to establish a scan path over the optical recording medium, and periodically deflecting the sinusoidal scanning beam in the first direction to linearize at least a portion of the scan path. By linearizing at least a portion of the scan path, two traces can be made per cycle of a primary sinusoidal deflection, thereby doubling scanning efficiency. |
