Hi All,

recently I had a problem with a portable MD battery failing on record
leaving no TOC on the disc, therefore lost all the recorded audio.

A fix was done using a Sony MD deck utilising the factory mode Test

It goes like this:

1) record a new MD (analogue silence) with one single track longer than the=

total length of the audio on the MD you need to recover,

2) After pressing stop, pull the mains plug on the recorder _before_ the TO=
is written.

3) Now Press the AMS knob while powering up. This puts the SONY MD recorder=

into a 'factory test mode'.

4) Eject the MD with the one track. It will not write the TOC at this point=

5) Put the MD you wish to recover in the deck.

6) Switch off the mains, then turn on again, but DO NOT hold the AMS knob
down on power up.

7) The TOC will be updated onto the problem disc.

8) You have now recovered the audio as one continuous playable track!

Hope this is useful. A variety of Sony mains MD recorders have this
