LiteOn LTR-32123S (32/12/40) CD-RW drive uses Zone-CLV for reaching 32x writing speed, however the final recording time seems that would be equal to what Mitsumi CR-480ATE (32/12/40) delivers. The drive reaches 32x using 4 zones: Starts writing at 16X, shifts up to 20X@6min, at 24X@16min and lastly up to 32X@41min...
