DISK DRIVE SPECIFICATIONS
HARD DISK DRIVES
OPTICAL DRIVES
TAPE BACKUP
For Real-time recording any hard disks or Optical drives must meet
minimum standards for access time and sustained data transfer. In other
words, they must be very fast.
For backup or non real-time applications, drive speed is not a usage limitation.
For backup, many drives will work, although you probably want to use
an optical disk or a tape backup.
The listing of recommended drives enclosed with your DM-80 gives
specific information about drives that have been tested with the DM-
80. Your dealer may have other, more up-to-date information regarding
compatible drives. The following gives general information about the
advantages and disadvantages of different types of devices.
Fixed disk drives, commonly known as Hard Disks, combine large
capacity with high speed at a moderate price. The most common type
of drive, hard disks are available in many sizes up to and beyond 1
Gigabyte (1024 Megabytes).
Optical disk drives are well-suited for backup since they store 320MB
(57 track-minutes @ 44.1 kHz) or more on each side of the disk.
By using the COPY PROJECT command, you can create backups of
your Project data onto optical disks.
Amm and 8mm Tape backup devices provide a cost effective method
for making backup copies of hard disk data.
