Tascam CD-D4000 owner manual Test write mode, Modes

2 - Modes

2.2 Test write mode

The test operation is functionally similar to the write operation, except that the writing of data to the slave disc is simulated. This is useful to make sure that data can be transferred at the selected rate between the master and slave discs.

1Press the MODE key until the display shows:

Mode select

2 Test write(4X)

2Press ENTER:

Test write(4X)

Ready ?

3Insert the discs into the disc tray (original in the MASTER, and the blank CD-R in the SLAVE), and press the ENTER key.

The test operation continues in exactly the same way as the copy operation described above.

Test Writing •

36%

The display shows the same messages, under the same circumstances, except that the word Copy is replaced by the word Test in all these messages.

At the end of the test procedure, the CD-D4000 does not simulate the writing of the TOC (the finalization process), and displays:

Test write

Finished

NOTE

There is one other important difference between test write mode and copy mode. You can interrupt the test write mode part of the way through the operation without affecting the slave CD-R media. If you interrupt a copy procedure part of the way through the opera- tion, the CD-R becomes unusable. To inter- rupt the test write operation, press and hold down the MODE key. The display will show Exit. When this is displayed, press the ENTER key. This cancels the test write pro- cess, and the display returns to the initial sta- tus screen. If you press the MODE key while Exit is shown on the display, the display returns to the test write display screen.

2.3Possible problems when copying or in test write mode

If the MASTER or SLAVE drive does not contain a disc, or if the disc cannot be read by the drive (it is upside-down or badly positioned in the tray), this dis- play will show No disc.

If the SLAVE drive does not contain a recordable CD-R disc, or a CD-R disc which has been previ- ously partly recorded, the display will show Bad disc.

The standard maximum length of an audio CD is set at 74 minutes. However, some commercial CDs are recorded with a running time a little longer than this. If the master audio CD exceeds 74 minutes in length (or the standard maximum amount of data (650 MB) for a CD-ROM), the display will show:

Master:Insuffi -

cient disc space

The message above will also be shown if the slave disc is of a smaller capacity than the source disc. In these instances, it is impossible to copy from the master to the slave disc.

If the master disc is scratched, damaged or unread- able for any reason, the copy process will halt, and the display will appear as below.

Error

Master:Bad disc

If the slave disc is scratched, damaged or otherwise unwriteable, the display will appear as below.

Error

Slave:Bad disc

If the copy operation is attempted at too high a speed, the display will show:

Buffer under run

In the event of any of these errors being displayed, pressing the MODE key will return to the main mode selection menu.

Correct the problem, if possible (replace the offend- ing disc correctly in the disc tray, try again with a dif- ferent disc, etc.) before attempting the copy operation again.
