Thank you for viewing. Used drive BDR-L13SH for Sharp recorders (BDR-L11SH, BDR-L12SH are also equivalent, so all can be used) Internal cleaning, oiling, and lens cleaning have been performed, and dubbing tests are also good. There are no special settings. Can be done with a single screwdriver. Ready to use immediately after replacement. This model has been tested to work with: BD-RE, BD-R, DVD-RW, DVD-R Also usable in recent models like BD-NS500, BD-NW500, BD-NW1000, BD-NW2000, BD-WW1000, BD-NT1000, BD-NT2000, BD-NT300, BD-NW520, etc., 2BC and 4BC types. Photos are reused, so an equivalent product will be shipped. Please contact me if you want a new one. It will be 15,000 yen. However, this is a used item, so please understand and proceed with the transaction. Can be done with a single screwdriver, but a putty knife or similar tool would be helpful. Ready to use immediately after replacement.
