Symptoms related to MD standard

Symptom

÷More than 255 tracks (track No. 256 or more) cannot be recorded. (There

may be also cases in which recording is impossible while the track number

is less than 256.)

In such a case, the REMAIN time display shows “0:00”.

÷When the remaining time of the entire disc is less than 12 sec, the

remaining time indication on the display becomes “0:00”. When the total

time of the deleted tracks exceeds 12 sec, the display changes to the

recordable time.

÷When a short track is deleted on a repeatedly edited disc, the remaining

time may not increase.

÷Connection of the track resulting from edit processing may not be

possible.

÷As recording is executed with 2 sec. as the minimum unit, the display time

may not coincide.

÷This derives from the restriction in the MD system standard and not a

malfunction.

÷Depending on the contents of the recorded source (CD etc.), the track

numbers may not be assigned correctly.

÷When a new recordable MD (with nothing recorded) is inserted,

“READING” is displayed longer than usual.

÷Monaural recording and stereo recording are executed according to

different formats. This is not a malfunction.

÷The title recording area is used in units of 7 characters, so that input of

1792 characters may not be possible.

Cause

“DISC FULL” is displayed while the disc still

has a remaining recordable time.

The possible recording time does not increase

even when a short track is erased.

Tracks can not be connected.

The time which has been recorded on the MD

and the remaining time do not add up to the

maximum recording time (60 or 74 min.).

When search is performed in a track which has

been compiled by editing, the sound is some-

times interrupted.

The track numbers are not assigned correctly.

“READING” is displayed for an abnormally

long time.

The time display becomes inaccurate with a

monaurally recorded disc.

Input of 1792 title characters is not possible.
