How to Repair a MiniDisc Recorder

Updated June 04, 2018

MiniDisc recorders provide users with a portable, easy-to-use method of audio recording. The MiniDisc recorder stores information on a removable disc that can be used by any MiniDisc device. As with any electronic equipment, the possibility of malfunctioning components within the hardware always exists. Fortunately, diagnosing and repairing problems on the MiniDisc recorder can be accomplished quickly.

Insert a MiniDisc into your recorder and press the play button. If the disc does not begin to play, this could be caused by a damaged or dirty laser unit inside the recorder. Several companies manufacture discs that are designed to clean the laser. After cleaning the laser, try playing your disc again. If the recorder is still unable to play the disc, the laser unit may need to be replaced. Contact a technician familiar with MiniDisc technology to discuss repair options.

Power on your MiniDisc device. If your recorder fails to turn on, this could be a sign of power supply failure. Many models of recorders are very sensitive to voltage levels. If you are using a voltage converter for your device, this may cause the power supply to shut down, as small changes in voltage levels can harm the power supply. Many audio equipment providers are available on the Web that can provide you with advice on where to purchase a new power supply.

Press the record button to test if your MiniDisc player is properly recording audio. If you do not hear the audio you have just recorded when playing back the disc, this could indicate a damaged recording head. Within the recording head, a small electromagnet is attached to a thin metal sheet using a single conducting mechanism. If your MiniDisc recorder is dropped or jarred, the conducting unit can easily detach from the electromagnet or metal sheet. Without this connection, the MiniDisc player will no longer record incoming audio signals. You may be required to purchase a new recording head to repair this problem.

Send your MiniDisc to a repair technician if you are only able to hear audio from one side of your headphones when using the recorder. It is very easy to inadvertently damage the input jacks on the recorder. Attempting to replace the input jack without the assistance of a repair technician may lead to further damage.


Prolong the life of your MiniDisc recorder by storing it in climate-controlled areas. Excessive heat or moisture can lead to technical problems with your device. In addition, routine cleanings of the laser unit can prevent damage to this delicate mechanism.


Avoid pressing the buttons on your recorder with excessive force. Much of the electrical equipment inside the recorder is housed in very close proximity to the outer shell. Excessive button pounding may bend the outer shell of your device and cause the internal components to malfunction.
