Question About High Speed Dubbing And Battery

[Guest tony wong]

I don't know which forum to post so I choose this one

I just bought a new md mini hi fi system CMT-333NT

1. is songs recorded from HIGH SPEED DUBBING mode in the bookshelf system?

I have seen an article say the songs recorded this way is actually LP2 or LP4 from mindisc.org before(but I just can't find the article again to prove it)

anyone have clues?

2. I have my player MZ-E710(it's a japanese version, u may not be able to find it in ur countries)

Used it for about 2 years(over 10hours a day, usually 10-14 hours a day)

and now, the battery(both NIHM and AA batteries) went out very fast

(but for AA battery it may still stand for 2-3 hours or even....say 6-7 hours)

is my sony rechargable battery(NI-HM1200) already worn out?

I usually won't charge it, I only charge it when I just bought this player

almost never charge the rechargable battery again

I only use AA battery, as I can buy it in the shops easily

is it the machine problem or battery problem?

I found a mysterious fact from this unit

(and I think it may be also true for the other player models that only play WHEN the RECHARGABLE battery is PLACED INSIDE OF THE UNIT, e.g. E610, N10)

that I found if the rechargable battery is not full and u attached the AA battery with the unit, the rechargable battery will becomes full after some times(say a few hours)

is it because there is a difference in volt or something like that which cause the unit to automatically charge the rechargable battery when u connect the unit with AA battery?

would it be possible that the unit is actually only using the power supply from rechargable battery(may be the circuit)....

that would mean....

we are using the rechargable battery even if it is not charged and empty,

and even when we are using the power of AA battery?

thx for any feedback first

Edit 1 : change the description

things to clearify :

1. high speed dubbing means 4x speed

2. as I remember, that article in minidisc.org say the actually recorded song on md is in LP2 or LP4 format

and, I am trying to find the fact by recording a disco song in both 4x speed and LP2 and LP4 format

look if I can find any difference

[Guest tony wong]

edited at a later time : I cannot be certain for that now

The following should be(but until now I still can't make sure) wrong, if u want to have a look, just highlight them

well, I think I have found the answer already

I think I'll have to state the reason why I am so aware of this thing

I do have a md mini hi fi already

the reason for me to buy a new one is just for the 2x/4x speed to dub my cd to md

and the old is not functioning very well.....

why I will discover this fact is because I just make a md copy from the Kylie Ultimate

and occasionally, I have used a new headphones as well

so I never notice the difference it made from the md recorded with my new md mini hi fi

then, I thought it was just my new headphone problem for the light bass

tonite I use my old headphone

then discover that, seems the treble part and the bass of these songs is weakened

(in fact, I have already discovered this thing before, but I have thought it is the failure of the album maker who haven't remastered the songs of the 1st disk of the Kylie collection

well, u know, songs recorded in the 90's may not be that good in quality)

then I remember I have read article about this thing before in minidisc.org

well, I'll have to say

the difference for SP and LP2 is actually not that noticeable

but, yes

u can only record in real SP mode(ATRAC compression but not ATRAC3 compression) with real time recording

any recording except 1x speed cannot produce real SP mode songs
