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. It can be done with a single screwdriver. You can use it immediately after replacing it. This model has been tested to work with: BD-RE, BD-R, DVD-RW, DVD-R It can also be used in recent models such as BD-NS500, BD-NW500, BD-NW1000, BD-NW2000, BD-WW1000, BD-NT1000, BD-NT2000, BD-NT300, BD-NW520, etc., 2BC and 4BC types. The photos are reused, so an equivalent product will be shipped. However, since it is used, please understand and trade with those who can. It can be done with a single screwdriver, but a putty knife or similar tool would be helpful. You can use it immediately after replacing it.
