Unfortunately, it is like this: iop old laser: 5.13ma iop new laser: 5:XXmA XX=missing numbers I have now read the service manual again but found some unclear information: you can call up 2 iop values in the service menu: you can save a new iop in the device and you can read out the labeled one from the pick-up. Would that mean that the sticker is not necessarily important because you can read the iop of the new laser or is it just that an iop value that was saved hard at the factory-process by Sony ?

Thank you very much for this valuable information. I really enjoy learning. Unfortunately I have no way of calibrating it and finding someone in Germany is extremely difficult. What a shame I thought it would be plug'n play if type b or e was swapped for the same. can you tell me what the abbreviation lob stands for? On the back there were 2 lines on the old 260e laser: 04411 and C0513. I assume the 513 is the lob. Unfortunately there was a sticker on the new laser so that only this information was visible on the new 260e laser: 06311 and 605** in the end that means to me that there is at most a 60 to 40 chance of having a laser change without a new calibration (for long-term satisfaction). Without the possibility of calibration, I would need tons of used MDM-7 and tons of new 260b and 260e lasers from different manufacturers or suppliers with the chance of different lob values. Somebody will fit... or is there an auto-calibration in the MDS-JE service menu? My only tools so far have been antistatic gloves, laser safety glasses (in addition to working without electricity), some videos and service manuals.

I was recently able to purchase a new laser duo 260B and 260E and yesterday I set out to replace the laser on my faulty MDM-7A. After disassembly you could see a 260E sticker on the underside. I was now able to replace the weak one with a new one and after installing it in JE770 everything worked fine. Just plug and play. I am so happy because there are now several ways for me to save a defective mds machine. Thank you for your expertise.

I am so pleased that there is a forum for the worldwide minidisc community (I'm from germany) to get still support for these great Sony machines. I have a MDS-JE770 and 780. my older 770 has inside as you all know the BD-board MDM-7A. This board has 2 possibilities for the laser unit: KMS-260B or 260E. These 2 different laser-units are working with different settings/adjustments for voltage and so on. Question: If I have an MDM-7A with a builtin KMS-260E: Will a MDM-7A exchange with a builtin KMS-260B work fine instantly "like a plug and play change" or are there settings / adjustments for the laser still to be done ? I think the answers will apply to the mdm-7S1A BD-boards as well (with 260B and E series)
