Answer Hi Eli, The status block transmitted from the disc you want to record contains data, describing the disc and the copy generation status. In your case the disc is described as CD (copy of original) with copy protection asserted, and no digital recording permitted. It does not mean that you have a non-original disc, it means that is was recorded so as not to allow even 1st generation digital recording. To overcome this situation visit Minidisc.org portal, you can find many solutions to bypass this problem. Truly yours,
Answer HI Ben To make the unit play longer, use the NH14-WM bat. It has longer life then the NH9, it is usually supplied with the MZ-R55. Regarding your back-light problem question. I wouldn't try to force a solution that involves introducing of new parts into the MD, or making any other internal modifications. Stay away from it and be happy as long as it still works. The MZ-R55 tends to make problems even without digging inside of it. If you must have light, use an external source or buy yourself an Aiwa MD with back-light. Truly yours
Answer Hi Ken, Thanks for your compliments. Regarding your problem. It is a well known problem. It can happen after the MD falls, or gets a mechanical shock to the earphone plug. If you are using the remote control plug the situation is better because the pressure on the earphone socket is lower. If you are not using the remote control plug you must check the earphone plug carefully before connecting it to the MD. If it is not perfectly round it can push the spring loaded contacts inside the socket more than it should. Even if you use good plugs it may happen that the connection of the socket with the printed circuit board becomes loose. All these things can cause the problem you described. In order to fix it you will have to resolder well all the contacts of the earphone socket to the circuit and carefully move the contacts toward the center of the socket. Check carefully that the printed circuit is not broken. If the situation does not improve you may have to replace the earphone socket. How to remove the bottom cover ?
Followup Hi David, I want to thank you for taking the time to make such a thoughtful and timely response to my e-mail about the headphone jack problem on my R55! I will try again, using your instruction, to get the bottom cover off and proceed! Perhaps I will e-mail or phone you sometime soon. Kindest regards,
Followup #2 Hi Again David, The problem with my R55 headphone connection is now fixed! It was a hairline crack in the jack tip solder point to the board. Thank you again so much for your excellent help! Cordially, Ken Horton Santa Monica, Ca.
Answer Hi Lee, Good question, difficult answer. When one says something is the best it is very easy to see that it is from his own point of view. In this sense, what is the best for me may not be the best for you. I'll try to answer.
The best machine for anybody depends on what he is expecting from it. If you are looking for the smallest unit, it is not the case of the MZ-R50. The Sharp MD-MT831, Sony MZ-R55/70/90/91 and other MD's are smaller. If you care for long play time with the battery it is not the case of MZ-R50; the others mentioned are better. If you need a reliable MD, one that will not break easily, with relatively high volume, a machine that doesn't suffer from all kinds of problems, stable with 40 sec. antishock mechanism choose the MZ-R50. I repair all kind of MD's daily, it is the only machine that is brought for repair due to age (normal) or a dramatic event (falling into the sea...) and not because of 'funny' symptoms which show that the MD's were brought to the market unfinished, or because of small events that created large problems.
Sharp MD's series 7XX: Almost all of them that come for repair have the UTOC ERROR problem. It is the most amazing thing I see daily. You own a new Sharp MD, you don't drop it, you use high quality discs, original power supply, in room temperature and one morning the display shows UTOC ERROR. The user manual says in those cases that the disc is bad or not clean and other funny jokes. Then you take the disc and place it in another MD and every thing is fine. So, how can we even consider to buy such an MD?
Sony MZ-R55: A small machine. It looks nice but nothing more. Press stop and in many cases it will start recording. Leave a recorded, unprotected, disc inside the MD during charging and you may find the disc was erased. Drop the machine from a few inches and it will stop recording completely. Use a non-exact power source and it will die partially or completely. Press a bit too hard on the keys and the whole cover will bend. How can we take such a creature seriously?
Sony MZ-R70/90/91: Beautiful MD's. All of them tend not to identify protected/unprotected disc. They all make internal loud and funny noises. Due to the special modus operandi the spindle motor is stoping very often (to save power) nobody told him that he must continue to revolve. I repair many of those that just stop with no prior alarm, usually at the high portion of the disc.
I can continue with Aiwa MD's having the 'CAUTION' announcement, similar to the UTOC ERROR, or the Sharp with the lever problem but let's go back to the MZ-R50. Looking on it with the MD Book of History you can see that it is based on older models of Sony. They learned the materia gradually. The 50 looks like the 30 and the 35 but it is better. They introduced a new laser unit and they built the MD from high quality materials. The covers are made from magnesium and the disc holder from titanium. It has the same weight as the MZ-R30 but is much smaller. It came out so well that Sony used the same mechanism for the MZ-R37 and for the MZ-R5ST. They used the same laser unit for the MZ-R55 but here it tends to break quickly, not as with the older brothers.
You see Lee it is not easy to explain. According to the gestalt theory the whole is more then the sum of its components, hold the MZ-R50 in your hand and you will understand what I'm talking about. Truly yours
Followup David, Thanks for the informative response! I only wish the MZ-R50 was still available new . . . Lee
Answer Hi Peter, As for now the MD format is not supporting unerase feature. I believe that in the future it will be possible in the same way it is done with our computers. This site gives some tips that may fix your problem: http://members.aol.com/BorusSylt/303.htm Truly yours
Answer Hi, Thanks for your compliments. As for your MZ-R90, what you experience is not a normal behavior of an MD. I found the same problem with an MZ-R91 (same as MZ-R90). It was completely new and behaved exactly as you describe. I cleaned it well (although it was not dirty), I made readjustment in test mode, lubricated it but all I can say is that it is a problem that was born with the MD. Something in the electrical or mechanical design is wrong. I found that the problem is more severe when using the external PSU. When running on its battery the situation is not so bad. One of our clients reported to me the same fact. If you are still under warranty go to the shop and try to get another machine. Truly yours,
