Mini Disc Problem

[Nitro27]

I have a MZ-N505, recently i put songs on it but the new songs i just added sounded bad (skip, scratches...) other songs are fine.

I tried to add them with another recorder to but it did the same so the problem is not my MZ-N505, and i think it may be the Mini Disc that is worn...but aren t mini disc supposed to last for 1 000 000 writings on it while i just wrote 20 times max on it...maybe the mini disc i'm using is just too old and new technology last longer

someone help me plz

Well yes, MiniDiscs are purported to last for 1000000 write cycles, but this is in a perfect envoronment, I would imagine.

That MD has probably just gotten some dust stuck in it over the years.

Or it is a Memorex.

no it's a sony

and it's really deceiving me.....

now i ll have to buy new ones and they'll do the same, 1 000 000 writings, yeah right!

bu can you guys write on it like it says it could or do you have a problem like me?

how many times did you write on it?

maybe it's an old model...

i mean, i didn t write more than 20 times!

I have some old Sony 60minute discs and even after rougly 8 years, they still work fine.

And they have more than 50 rerecordings through.

Btw, the 1 million times is in reality a different thing:

It means 1 million passes of the recording head on the same spot.

During recording ( and always in portables ), a tiny magnetic head touches the top surface of the disc,

changing the phase polarity of the recording layer, while the laser heates the spot from below.

The problem here, if too much dust/dirt is on the disc, the recording head is lifted off the disc, reducing the recording level.

The same happens, if the disc is well beyond the 1 million mark, since the top surface becomes rough,

the head cannot keep smooth contact with the disc.

How fast can you reach the 1 million passes? If you play the disc once per day, you need roughly 2000 days.

Unless dirt and dust enters the disc.

Dirt and dust acts like sandpaper, so store the discs at a clean place and keep them in the supplied jackets/boxes.

But that's good practice anyway.

ok thanks for the info!

but I'm still a bit suprised about the dust thing, i always kept my mini disc inside my player.....anyway, let's wish more luck next time

[jadeclaw]

Does that mean, you have just ONE disc?

I suggest, getting a bunch of them and keep them filled, so that you simply grab the one you like and take off.

They're cheap nowadays.

I agree, if your using just one disc then like Jade said, your going to wear it out more quickly. Its kind of like a cassette player, you can only record so many times, and playing 'streches out the tape'.
