Recording method and REMAIN indicator

Recording method

The recorder uses a E-IDE hard disk instead of a cassette tape. You can start recording sound sources from any point on a formatted disk as long as the point is within the range of 24 hours in ABS time, as described in the previous “Time Base” section. (Refer to the following diagram.)

							REC END		23h, 59m, 59s
ABS 0		03m 00s 00f		10m	00s 00f		12m 00s 00f
	recorded area (3 min.)		unrecorded area			recorded area (2 min.)		unrecorded area

You can record at any point within 24 hours in ABS time.

The area actually used on the disk.

recorded area (5 min.) unrecorded area (25 min.)

recordable disk area (e.g.: 30 minutes)

You can record at any point within 24 hours in ABS time.

White areas are unrecorded areas.

Gray areas are recorded areas.

For example, if you record three minutes of data starting from ABS 0 (top of the disk) to ABS 03m 00s 00f on a disk that has a recordable space of thirty minutes, as shown in the diagram, then if you record two minutes starting at the 10-minute point in ABS time (ABS 10m 00s 00f) to ABS 12m 00s 00f, the recording end point (REC END) is 12 minutes (ABS 12m 00s 00f) in ABS time. However, this does not mean that the entire recording duration is 12 minutes. The disk space actually used for recording is five minutes (3 minutes + 2 minutes).

That is, the area between three minutes and ten minutes (that corresponds to 25 minutes of recording space) in terms of ABS time is still unrecorded.

When you try to play or fast forward this unrecorded area, the time counter on the display will count, but the recorder will not access the disk. However, MTC will be output when you try to play this area. On the recorder, the top of the disk is called “ABS 0” and the recording end point is called “REC END.”

REMAIN indicator

The REMAIN indicator displays available recording time expressed in time value (ABS or MTC) or bar/beat/clock (BAR/BEAT/CLK) value, depending on the currently selected Time Base.

It also indicates the available disk space. Right after you format the disk, the REMAIN indicator will show the maximum recordable time and space on the disk. The following example shows that the disk had about 3 hours recordable space after the disk format operation, and has recorded data of 2 hours 48 minutes 57 seconds.

The REMAIN value is calculated on a mono-track basis. That value indicates the available recording time and space if you record on one mono-track.

For example, if you wish to know how much you can record on eight tracks, you need to divide the current REMAIN value by eight.

The REMAIN value display is calculated from data on the real track and data on the additional track which will be explained later, and includes data left over for multiple undo. In other words, the REMAIN value will be displayed in the form of time/capacity obtained by deducting data on the real track, data moved onto the additional track and past editing data left over for multiple undo.

As described in “Managing the song by Program,” the recorder can set up as many as 99 Programs on the disk. Setting up a Program requires a small amount of disk space. In other words, disk space is used not only for storing recorded data but also for storing all setup data. Therefore, make sure that you have enough space on the disk before you start recording to avoid running out of space (the [OVER !] message flashes in that case).
