Pressing DAT OPTIONS (F1/F2) gives this screen display:
Here you may select which of the digital I/Os you will use for the archive/restore. For
restoring, you may choose between DIG A or B (or if optional digital I/Os are fitted, DIG C
or D) and for archiving, you may select MIX A or MIX B outputs.
You may also set the tape length of the DAT you are restoring to and you may choose
between DAT 30 (30 minute tapes) to DAT 180 (3 hour tapes). The archive process uses
the stereo capacity of the DAT tape so a DAT 120 can hold 4 hours worth of material (you
can do your own maths for the other tape lengths!).
To perform the archive, insert a blank DAT tape into the DAT recorder and make sure it is
rewound to the start. Put the DAT recorder into 'record pause'. Get the DD1500 ready for
archive, 'unpause' the DAT and then press ARCHIVE (F5/F6) on the DD1500. The
archiving process will begin.
If the tape runs out during the archive, you will be prompted to insert another.
The time taken to archive is just a little longer than real-time (i.e. one hour of material will
take just over one hour to archive). However, please note the capacity of DAT for archiving
purposes. A DAT 60 can hold approximately 600Mb of data making it a bit too small to
archive one side of a 1.3Gb MO disk (650Mb - approximately 2 hours of audio at 44.1kHz)
but because a DAT 90 can hold approximately 900Mb you could easily archive one side
of a 1.3Gb MO disk to such a tape. A DAT 120 could be used to archive a 1Gbyte hard
disk. Larger hard disks will need to be archived over several tapes and you may prefer to
archive your projects and/or libraries individually in this case as you can organise the order
you want the items archived and decide which tapes you want them on. Furthermore, with
single files archived in this way, when you come to restore, you don't have to do the full
restore but you can selectively restore projects you are interested in.
** IMPORTANT NOTE ABOUT RESTORING SINGLE ITEMS **
YOU CANNOT RESTORE A SINGLE PROJECT/LIBRARY TO A DISK TO ADD TO OTHER
The restore process first erases the disk and then restores the audio onto the disk. In
other words, you cannot make a compilation of projects and libraries from different archive
tapes onto one disk because each time you restore an archive, the disk will be erased.
Please ensure that you use a blank disk (or one you are happy to erase) when restoring.
AKAI ELECTRIC CANNOT BE HELD RESPONSIBLE FOR DATA LOST IN THIS WAY.
