INTRODUCTION This document presents the engineering specifications of LSC-24082K Combo drive. The Combo drive, featuring high speed, power-saving and slim size, is built specifically for notebook computer. The unit measures 12.7 by 128 by 126.1mm and weights below 190g. LSC-24082K is a versatile optical disk drive. For write function, it is capable to write data, which conform to Orange Book: Part 2 CD-R Volume 1 / Part 2 CD-R Volume 2 Multi Speed / Part 3 CD-RW Volume 1 (known as Low Speed) / Part 3 CD-RW Volume2: High Speed / Part3 CD-RW Volume 3: Ultra Speed, into CD-R/RW disk in combination with write application software. For read function, it is capable to read all of the following file formats of media: DVD single/dual layer (PTP, OPT), DVD-R, DVD+R, DVD-RW, DVD+RW. Besides, it reads all of CD formats and media: CD-DA, CD-ROM, CD-ROM/XA, Photo-CD, Multi-session, Karaoke-CD, Video CD, CD-I FMV, CD Extra, CD Plus, CD-R, and CD-RW. The drive supports a DVD-ROM data transfer rate of 8X in the outer track, 3.3X in the inner track, and achieves 6X speed in average for a 12cm disc. For CD-ROM data transfer rate, it supports 24X in the outer track, 10.5X in the inner track, and achieves 19X speed in average for a 74 min disc. Besides, SMART-X function smartly adjusts CD-DA / VCD / DVD data extraction to a fastest allowable speed according to both data request rate from host and disk quality. Regarding to write speed, it supports 24X writing and 24X re-writing. For writing/ ® rewriting, SMART-BURN function can avoid buffer under run as well as get the best writing quality by smartly adjusting writing strategy. LSC-24082K is a multi-function drive with power saving, slim size and ultra light weight that it meets notebook computer as well as all kinds of compact or external applications.
