Additional Information

System Limitations of MDs

The recording system in your MD deck has limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes.

“DISC FULL” lights up before the MD has reached the maximum recording time (60 or 74 minutes)

When 255 songs have been recorded on the MD, “DISC FULL” lights up regardless of the total recorded time. More than 255 songs cannot be recorded on the MD. To continue recording, erase unnecessary songs or use another recordable MD.

“DISC FULL” lights up before the maximum number of songs (255) is reached

Fluctuations in emphasis within songs are sometimes interpreted as song intervals, increasing the song count and causing “DISC FULL” to light up.

“TOC Reading” is displayed continuously

The “TOC Reading” display lasts longer than usual when a brand new disc is inserted.

The total recorded time and the remaining time on the MD do not total to the maximum recording time

This unit displays the length of the largest continuous blank area as the remaining time. Therefore, if there are several separate blank spaces, the remaining time will only display a time equivalent to the largest continuous blank space.

If there is a 1 minute blank space and a 2 minute blank space, the remaining time display will be “2” minutes. If you then record 1 minute and 30 seconds of the 2 minute blank, the remaining time display will become “1” minute.

It is not possible to make new recordings on a song which was modified using the Section Edit or Song Combine functions

In this case copy the entire song (using Song Copy), then perform the desired recording or edit operation on the new copy of the song.

It is not possible to shorten part of a song using the Section Edit or Song Edit functions

This unit organizes the audio data in sound groups and clusters. The minimum size of these units varies according to the number of tracks specified in the system setting (page

17). With 4 tracks, units may not be less than approximately 4 seconds. With 2 tracks, units may not be less than approximately 8 seconds. With 1 tracks, units may not be less than approximately 16 seconds.

Discs with Emphasis information are not properly De- emphasized during playback.

During playback and recording, this unit always handles emphasis information as if it were turned “OFF”.

Unit enters the play/pause mode between songs during continuous playback.

This unit enters the play/pause mode momentarily before resuming playback each time it reaches a new song number or division created using Song Divide.
