Abstract: A method used in a CD-R/W drive for coordinating the writing and reading speeds of a CD-R/W drive is disclosed. With the aid of the method, the writing speed of the CD-R/W drive is able to be adjusted, and thus a more stable writing operation is obtained. In the method, if the time(s) that the buffer has been cleaned up is/are not larger than the predetermined value, the CD-R/W drive will write data to the CD-ROM at its highest speed. On the contrary, if the time(s) that the buffer has been cleaned up is/are larger than the predetermined value, the CD-R/W drive will slow down stepwise from the current speed to a lower speed. To accomplish the invention, the CD-R/W drive is either controlled by computer programs or by a programmably pre-written control chip that is installed in a control circuit inside the CD-R/W drive itself.
