How do I clean tape heads?
To clean tape heads, use pure isopropyl alcohol and lint-free swabs. Throw the swab away after use.
How do I demagnetize tape heads?
Practical tape head demagnetizers are available for under $10. Try to find one with a plastic coated tip. If you can't find one which is plastic coated. you can slip a drinking straw or plastic tube over the tip for the same effect. This plastic will prevent the demagnetizer from scratching the head.
Before plugging in the demagnetizer, remove all tapes from your working area and unplug the recorder. Hold the demagnetizer away from the recorder as you plug it in. Slowly bring the tip of the demagnetizer up to the tape head and slide it back and forth across each tape head for five one-second strokes. Then pull it away from the head slowly and go on to the next. After demagnetizing the heads, use the tip on each metal tape guide with a similar five strokes. Last, slowly pull the demagnetizer far away from the recorder and unplug it. Recording engineers use a demagnetizer before each recording session. (courtesy of AudioFAQ)
How does bias fine tune work?
The bias fine tune only changes the sound during the recording process. Variable bias is a compromise to adapt the deck to different tape brands. It is most useful for type 1 (normal) tapes. You make a recording, and then compare in playback to the source. If the recording sounds bright, turn the bias knob clockwise 30 degrees and make another recording. Dull? Turn the knob counterclockwise. You can also test by recording FM inter-station hiss, but keep Dolby off and keep record levels at about -20dB. (courtesy of Tom Brucker)
Closed-Loop Dual Capstan Transport?
A closed-loop dual capstan transport mechanism ensures smooth, precise tape traveling and as a result excellent sound reproduction.
My deck needs new belts, where can I buy these?
A good source is eBay. There are quite some sellers that sell dedicated belts for certain decks. Look inder the 'for sale' tab for current eBay items for sale for your deck.
What's the strange cage around the play head on the dual capstan units?
It lifts the fibrous pad inside the tape in order to prevent scrape flutter--the bouncing of tape across the head--the result of uneven pressure on the tape. These pads are installed to put pressure on the tape to keep it in contact with the head in most machines but are not as consistent as the high-quality transport of the Nakamichi.

What is assymetrical dual capstan?
Dual Capstan refers to the metal posts that you see down by the heads. A single capstan deck only has the metal/rubber wheel assembly on one side. A dual has it on both. Dual assists in more linear tape travel across the heads and results in less variances in the recorded/playback signal. The assymetrcial means the capstan flywheels are different sizes, and therefore, rotate at different speeds. The result is greatly reduced wow and flutter and stable pitch. Still, a Nak single capstan machine "is driven by a flat belt which ensureseven tension and accurate torque transmission from it DC servo motor." Almost without exception, a single capstand Nakamichi sounds better than the majority of other brand's dual capstan decks. (courtesy of Nakamichi Cassette Deck FAQ)
Are the dual capstans supposed to spin all the time while the unit is on but stopped?
Yes. This assures tape speed will be accurate open hitting play (courtesy of Nakamichi Cassette Deck FAQ)
What does discrete head mean?
The erase, record, and playback heads are all individual components. The result is better recording and playback as each head is dedicated to its specific job as compare to a 2 head which uses a common record/playback head whose function is determined by a switch or relay. Most three head machines allow for immediate monitoring or recorded signal with the exception of the 481, 581, and 681ZX. These machines have the sonic fidelity of a three head without the convenience or cost. (courtesy of Nakamichi Cassette Deck FAQ)
What has Nakamichi done to keep their machines from "eating" tapes?
A: They have a tape motion sensor that will stop the machine if the tape has stopped moving for any reason. (courtesy of Nakamichi Cassette Deck FAQ)
