ABSTRACT:
A method and apparatus for pausing a video presentation in a recordable disc medium device is provided wherein the recordable disc medium device utilizes its capability to read data at a variable rate to increase the overall average bit rate. The disc medium device can record the video presentation on the disc medium at a selected location and can periodically interrupt this recording to read from the disc medium a portion of the recorded video presentation. Additionally, the recordable disc medium device can vary the rotational speed of the disc medium to enable the disc medium device to alternate between reading and recording. While the speed of the disc medium is varying, the recordable disc medium device can read recorded data at a variable bit rate. This process increases the overall average bit rate thus enabling the disc medium device to playback and record the video presentation seamlessly.
