Korg D1200 4. Drive capacity, 3. Erasing a CD-RWdisc

3. Erasing a CD-RW disc

This operation erases the data that was written on a CD-RW disc.

Erasing a disc lets you use the entire capacity of the disc, just as when it was unused (blank).

When you execute “EraseCD-RW,” all data will be erased from the CD-RW disc.

“EraseCD-RW” cannot be executed on a drive other than a CD-RW drive.

1Insert the CD-RW disc into the CD-R/RW drive.

2Select “EraseCD-RW.”

•Select “SelOperation,” and use the [VALUE] dial to select “EraseCD-RW.”

3Execute the erase operation.

•Select the “Exec.” button and press the [ENTER] key to open the dialog box.

•Use “Quick” to select how the disc will be erased. If you turn this “On,” the entire CD-RW disc will be erased at high speed. Normally you will select this. If you turn this “Off,” the entire CD-RW disc will be erased completely. Use this if you experience a prob- lem such as if the disc fails to be recognized even after it has been erased with “Quick” turned On.

•Press the [YES/OK] key to begin the erasing opera- tion.

•When formatting is finished, the display will indicate “Completed.” Press the [YES/OK] key.

CD-RW discs can also be erased in the [CD] “CDR/RW” tab page.

4. Drive capacity

This section explains how you can make the best use of the D1200’s song drive capacity. For explanatory purposes, we will assume that you have recorded a song with the following structure.

Intro A B Break Solo Ending

The Optimize Track operation described here does not need to be performed often. It is sufficient to perform this operation when the “DiskBusy” indication appears, or when you want to recover disk drive capacity after completing a song.

Example 1: You began recording on track 1 from the beginning of the song, and only played during the Intro, Break, and Ending on the first take.

Intro Silence Break Silence Ending

In this case, silence (actually, noise-level sound) will have been recorded in the A, B, and Solo sections of track 1, unnecessarily using up valuable drive space.

To keep the audio data only for the Intro, Break, and Ending that you are actually using

Execute the Optimize Track operation on track 1, from the beginning of the song to the end of the song. Set the Optimize Track “Mode” parameter to “Erase Silence,” and execute. This will cause audio data to be preserved only for the actually-used regions, so that only the intro, break, and ending will occupy drive space.

	Intro	Data exists		Break	Data exists	Ending
IN			“OptimizeTrack”			OUT
		After execution
	Intro	Data erased		Break	Data erased	Ending

Example 2: You began recording on track 1 from the beginning of the song, and played the Intro, A, B, and Break during the first take, and then recorded a second take to overwrite A’ and B’.

1st take	Intro	A	B	Break
	Recorded second take
1st take	Intro	A	B	Break
2nd take		A'	B'

In this case, A and B of the first take remain “beneath” A’ and B’ of track 1, in order to preserve the data for Undo and also because they are a continuous piece of audio data with the Intro and Break. This means that Intro, A+A’, B+B’, and Break are occupying disk space.
