KR950009567A - Recording control device and method of optical disc - Google Patents

Abstract

The present invention relates to an optical disc recording control method and apparatus, wherein the amount of source data transmitted exceeds a recording capacity of one recording medium, and a method and apparatus capable of recording a digital data without loss of data transmitted during exchange of the recording medium. For the purpose of the disclosure. The present invention connects the source data and the recording drive with the direct transfer path, and simultaneously connects the buffer memory in the middle and connects them with a separate transfer path, so that a large amount of source data is insufficient for one recording medium. During the preparation of the recording, the data transmitted temporarily is temporarily stored in the buffer memory and then rewritten to a new recording medium.The control means transfers predetermined control signals to the recording drive and the buffer memory according to the commands of the microcomputer and the microcomputer. It is composed of a control unit to provide. The present invention is expected to be effective in that it can record without loss of data even when a large amount of data is transmitted and the user cannot control the data burnout.

Claims (6)

Temporary storage means for temporarily storing the source data that is applied to the data source by the first transmission path, and data that is connected to the data source as the second transmission path and simultaneously connected to the temporary storage means by the third transmission path. A recording drive for recording a recording medium on a recording medium, and the temporary storage means and the recording drive connected to the recording drive, the source data being directly applied to the recording drive through the second transmission path if the remaining capacity of the recording medium being used is greater than or equal to a predetermined size. If the size is the same, the source data is transferred to the temporary storage means through the second transmission path during the exchange of the new recording medium and then the source data is transferred to the temporary storage means through the first transmission path during the exchange with the new recording medium. After that, when the new recording medium is ready for recording, the source data again returns to the second transmission path. And recording control means for controlling the source data stored in the temporary storage means to be applied to the recording drive through the third transmission path when the last of the source data is transmitted. . An apparatus as claimed in claim 1, wherein said temporary storage means uses a buffer memory. 2. The apparatus of claim 1, wherein the recording control means comprises a microcomputer for reading a state of a system and providing a command regarding an operation, and a control unit for providing a predetermined control signal to the recording driver and temporary storage means according to a command of the microcomputer. Optical disc recording control device characterized in that. The optical disc recording control apparatus according to claim 2, wherein the microcomputer calculates the amount of data stored in the temporary storage means so that the space corresponding to the amount of data is left to be interlaced and recorded. An optical disc recording control method for receiving source data and recording on a plurality of recording media, wherein if the remaining amount of the first recording media is equal to a predetermined amount while the source data is directly recorded on the first record medium, the data recording destination is changed. A first process of recording by switching from the first recording medium to the temporary storage means; and when the preparation of recording of the new second recording medium is completed while recording to the temporary storage means, the data recording destination is switched back to the second recording medium to perform the recording. A second process of recording an area as much as the amount of data recorded in the temporary storage means, and recording the data stored in the temporary storage means when the last source data is applied and the recording is completed on the second recording medium. And a third process of recording in the blank area of the second recording medium. 6. The optical disc according to claim 5, wherein the predetermined amount of said first process is larger than the amount of data that can be recorded for a time necessary for at least reading from the remaining recording amount until switching of the recording destination is completed and a recordable state is ready. Record control method. ※ Note: It is to be disclosed based on the initial application.
