摘要： A light-tight optical disk cartridge is disclosed for use with ETOM erasable and other optical disks in which light baffles incorporating a snap lock feature are utilized in the assembly of the optical disk cartridge in order to provide structural integrity to the cartridge as well as to prevent the entry of light into the cartridge. A snap close slide and latching mechanism is incorporated in order to prevent accidental opening of the access mechanism of the optical disk cartridge.

摘要： An optoelectronics apparatus selectively drives a light source, and includes four electrically isolated photodetector (PD) segments that detect light that has reflected off an object. Each of the four PD segments produces a corresponding signal, referred to as signals A, B, C and D, indicative of the light detected by the respective PD segment. Circuitry is used to produce a first motion signal indicative of a sum of the signals A plus B minus a sum of the signals C plus D, i.e., the first motion signal is indicative of (A+B)−(C+D). Further circuitry produces a second motion signal indicative of (B+C)−(A+D). Additional circuitry produces a signal and/or data that is indicative of a direction and/or rate of motion of an object, in dependence on the first and second motion signals.

摘要： An apparatus and method are disclosed for piecemeal recording of data on an optical disc using a spiral track format without the necessity of leaving a guard band between recordings or even providing a leader on the subsequently recorded track. A new recording is added to the end of a previously recorded track by first playing back the previous track. The tracking servo is locked to the data track and the translation stage motion is adjusted to match the spiral rate of the track. As the end of the previous track is approached, the translation stage drive is switched to a constant dc drive, the tracking servo is disabled, the tracking mirror is electronically locked to a nominal position, and the new recording begins. This operation may be repeated for each new data file to be recorded in piecemeal fashion.
