Optical disk control apparatus |
摘要 |
An optical disk control apparatus which makes it possible to record and play back the data of a sector when a sector signal representative of the start of the sector is missing. A timer detects an overtime in the time intervals between sector signals due to a missing sector signal due to a defect in an optical disk or the like. A one-shot circuit is provided to produce a simulation sector signal similar to the normal sector signals when an overtime is detected. A combining circuit is connected to receive either the normal sector signals or the simulation sector signals and delivers the signals to a control circuit so as to enable the control circuit to operate the apparatus continuously. |
