Tho Rvordinj; svstom in vour MiniDisc Rvordor is radicallv dittoront trom those used in
cassette and DAT decks and is characterized b\' the linhtations dL'scrilx\1 lx'!i>\v. Note,

liowe\ er, that these limitations are due to the inheretU nature ot the MD recording s\ stem
itsi'lt and iH>t ti> mechanical causes.

Symptom

"TR FULL” appears even

before the disc has reached the
maximum recording time (60 or
74 minutes).

Cause

When 254 tracks ha\ e been recorded on the disc,

"TR FULL" appears regardless of the total
recorded time. More than 254 tracks cannot he
recorded on the disc. To continue recording, erase
unnecessary tracks.

"TR FULL" appears e\’en

before fhe disc has reachexi the
maximum track number or
recording time.

Track marks cannot be erased.

Repeating recording and erasing may cause
fragmentation and scattering of data. Although
those scattered data can be read, each fragment is

counted as a track. In this case, the number of

tracks may reach 254 and further recording is not
possible. To continue recording, erase
unnecessary tracks.

When the data of a track is fragmented, the track
mark of a fragment under 12 seconds long cannot
be erased.

The remaining recording time
does not increase even after
erasing numerous short tracks.

Tracks of under 12 seconds in length are not
counted and so erasing them may not lead to an
increase in the recording time.

The total recorded time and the
remaining time on the disc may

not total the maximum
recording time (60 or 74
minutes).

Recording is done in minimum units of 2 seconds
each, no matter how short the material. Even if
the last unit of recording is less than 2 seconds, it
is counted as a unit of 2 seconds. Then 2 seconds'
space is put before recording starts again to

prevent the last unit of the previous track from
being erased. The contents recorded may thus be
shorter than the maximum recording capacity.

The edited tracks may exhibit
sound

dropout

during

search

operations.

The fragmentation of data may cause sound
dropout while searching because the tracks are
played in higher speed than normal playback.
