CAUTION
Hot Surfaces on Recording Media
During extended operation, high data rates and/or operation at high ambient temperatures,
the recording media in the camera can get hot to the touch and can cause pain or even
burns if held for too long directly after removal.
Do not handle the recording media for longer than three seconds and remove it quickly but
carefully.
Consider to wear protective gloves when removing the recording media or allow it to cool down
beforehand.
Do not put any labels or adhesive tape on the recording media (especially the side facing the
camera body). The recording media must have full contact to the thermal surface inside the
camera to ensure proper heat conduction.
ADVICE
Recording Media Damage due to improper Handling
Damage to the Recording Media or Loss of Data.
Always insert the recording media as described in this document.
Keep the media door closed to prevent dirt and moisture from entering the camera.
Do not put any labels or adhesive tape on the recording media. The metal surface is used for
cooling. A hot medium can have reduced performance. The plastic surface can easily be broken
off when a label is removed.
Never remove a drive while recording - this may damage the recorded clip.
If the recording process is interrupted by power loss or drive removal, transfer all the data from
the drive and format it before using it again.
While we do everything we can to assure reliable functioning of different recording media such
as Codex Compact Drives, and while the mean time before failure (mtbf) for drives is excellent, a
failure that results in loss of data may occur at any time. Therefore, you are obliged to implement
and maintain at any time adequate and necessary data security measures and back up drive
content as soon as possible. ARRI assumes or accepts no liability or responsibility for data loss
or data corruption, or any other damages, loss or harm due to malfunction of recording drives.
ADVICE
A maximum of 400 clips can be recorded on a drive. When the maximum of 400 clips is reached, the
recording media will be declared as full and further recording onto the media is not possible.
Codex Compact Drives
The Codex Compact Drive is designed to support the demands of creative professionals working with
the ALEXA Mini LF and the ALEXA 35. It offers robust mechanical protection, efficient cooling and a
reliable connector for the integrated, high speed flash memory.
Compact Drives are currently available with 1 TB (960 GB usable) and 2 TB (1920 GB usable)
capacity. The 2 TB drive offers about double speed for all ARRIRAW formats on ALEXA 35. There is no
advantage other than capacity for the Mini LF. At 24 fps ARRIRAW 4.6K 3:2 Open Gate, the recording
time is a little over 25/50 min. At 24 fps Apple ProRes 4444 4K 16:9, the recording time is a little over
90/180 min.
