LTD163D or LTD166S

Could anyone tell me the difference between a Lite-On LTD 163D and a Lite-On LTD 166S?

Do they both read: DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-RAM?

At the internet page of Lite-On I can’t find specific differences.

The 166S reads DVD-Multi, the 163D doesnt.

This is a “changelog” for the 166S that was posted by Nicowico some time ago.

  1. User protection against fragment of crashing disc :
  • New top cover with folding edge
  1. Acoustic noise improvement
  • No damper screw hole on tray
  • Stream-line design of chassis loader to reduce noise induced by air flow in the drive
  • New bezel and top cover design
  1. IDE cable Short prevention
  • Isolate IDE connector and bottom cover to prevent IDE cable short caused by direct contact with bottom cover
  1. Disc scratch free design
  • New tray design with contacting slope to prevent disc scratched by tray in OD area.

Essentially, it protects you from exploding discs (didn’t Lite-On say they weren’t really concerned about this?) and its quieter.

Improvement of LTD166S

  1. Tray in out noise improvement
  • Improve precision of center distance and grade of gears.
  • Optional dual driving type ( gears train /belt).
  1. Better dust proof
  • No slots around screw hole on bottom cover.
  • Labyrinth dust-path design on chassis.
  • Flatness spec. improvement of bezel and door.
  1. Better ESD/EMC margin.
  • Protection wall on tray motor.
  • Front screw holes are closer to bezel.
  1. Better non-op shock and drop capability

LTD-166S : Traverse design

  1. Symmetric suspension points ( good for vibration).
  2. Light weight ( good for vibration)
  3. Strong structure against drop or shock

What’s DVD multi?

DVD-Multi means the drive can read DVD-R, DVD-RAM DVD+RW and so on.

So the big difference is: the LTD 166S reads everything (DVD-R, DVD-RW, DVD+R, DVD+RW and DVD-RAM) and the LTD 163D can only read …?? At least not all. Am I right?

Yep, that’s about right.
