Our CD-R and CD-RW go well beyond the craze of the market to meet various needs of both the hobbyists and the industrial professionals. Put our disc in any drive, either branded BANKA? or bulk spindle pack to perform the task, and see for the impressed proof of satisfaction in quality. We have also created extra marketing values for the ordinary CD-R by colouring the recordable side by using attractive fancy coloured dyes. This is a technologic issue we have to overcome because the transfer rate of the writing (recording) laser beam will be affected by the dark colour dye. Our black dyed CD-R will have lower speed in average of 40X whereas the other colours can reach to 48X speed. To extend further, we have engineered the ordinary CD-R to a unique 3D Theme Recordable Discs which is specially designed with particular purpose of containing promotional catalogues, advertising news, company or personal details, festival events, etc. I) Characteristics: Storage capacities include 21min/185MB, & 80min/700MB. 52X speed or above for regular 12cm, 8cm, other smaller writing capacity, such as business card shape, or credit card shape, and 1X-24X for theme CD-R.
