General Information 1-15
1.
Use only HP-approved discs. Use of any others can result in damage to the drive
mechanism, high maintenance costs and data loss.
2. Return the disc to its storage envelope and replace in the box whenever it is removed
from the disc drive.
3. Replace storage envelopes when they become worn, cracked or distorted.
4. Do not touch or attempt to clean the surf ace of the disc. Abrasions may cause the loss
of stored data.
5. Do not write on the plastic jacket of the disc with a lead pencil or ballpoint pen. Use a
felt-tip pen and write only on the label.
6. Do not expose the disc to extremes of temperature or humidity.
7. Keep the discs away from magnetic fields and ferromagnetic materials that may be-
come magnetized. Strong magnetic fields can destroy the data recorded on a disc.
Write Protect
The disc has the capability of being write protected. This feature prevents the accidental
erasure of data recorded on the disc. The write protect feature is enabled when the write
protect notch on the cover of the disc is uncovered (see Figure 1-7). When the notch is
covered, writing is allowed on the disc.
The write protect notch may be covered by placing a tab over the notch on the top side of
the disc jacket and then folding the tab over the edge to cover the notch on the bottom side.
The installation of the tab is shown in Figure
1-7.
The notch must be covered with an
opaque material, as it is sensed optically.
