Label paste position

30 AIT Data Cartridge

Precautions on entry to label

• To represent the data contained in the AIT data cartridge, use a label which can be easily
replaced and no adhesion trace is left.

• To change the label indication, do not erase it with an eraser but peel the old label and paste a
new one. (The INDEX labels are provided with the AIT data cartridge.)

• Pasting the label in the position specified in the previous section. To replace the label, peel the
old label and paste a new one.

• When using a label other than the specified INDEX label, its size should be the same as the
specified label.

• Enter the date when starting to use the cartridge in the provided INDEX label. It will help you
check the AIT data cartridge service life.

Precautions on Handling

Operational precautions

Before use

• If the AIT data cartridge is damaged, deformed or bent, do not use it.

• If the AIT data cartridge is exposed to an environment other than the operating or storage
environment, expose it to the operating environment for a longer time than the period when it is
exposed to other environment (for 8 hours at maximum) before use. If temperature is greatly
different between the storage site and the operating site, do not rush the cartridge into the
operating environment. Leave the AIT data cartridge in temperature of the operating site with
temperature gradient set to 10 °C/hour.

Mounting to the Built-In AIT Auto-Loader Unit

Set the cartridges as explained in “Setting the AIT data cartridge”. Close the empty protective case
firmly and store it in a place free of dust and dirt.

After use

Be sure to put the AIT data cartridge that you used in the protective case and store it in a place free
of dust and dirt. You can place it horizontally or vertically.

General precautions

• Do not touch the memory terminal (refer
to P. 29).

• Do not touch a tape by hands. Do not
open or close the tape cover.

• Do not bring a substance which generate
magnetic close to the cartridge.

• Do not place the cartridge in a place
subject to direct sunlight or a place near a
heater.

• Do not apply strong shock.

• Avoid handling the cartridge while eating
or drinking. Take due consideration not
to adhere thinner or alcohol to the
cartridge.

Tape surface

Tape cover

• Insert the cartridge to the Built-In AIT Auto-Loader Unit gently and carefully.

32 AIT Data Cartridge

Usage Inhibition Standard

If an AIT data cartridge that you are using is in the case below, you must replace it.

• When the AIT data cartridge is given a strong shock, for example, when falling, and damaged.

• When the recording surface is contaminated with liquid, such as soft drink, coffee and tea,
detergent, metal chips or cigarette ash.

Important

If you insert an AIT data cartridge in such a condition into the Built-In AIT Auto-Loader Unit, the
read/write head or the driver itself may be damaged or contaminated, causing a machine failure.
Also, if you insert a new AIT data cartridge into the Built-In AIT Auto-Loader Unit whose head is
contaminated or scratched and you do not know about it, the AIT data cartridge may be contami­nated or damaged. In this way, damage is expanding.

Service Life

The service life of the AIT data cartridge varies greatly depending on temperature and humidity in
the operating/storage environment, dust and dirt, and head abrasion condition.

You can judge its service life in the following sequence.

• Assign a management number to a new AIT data cartridge. Enter the number in the AIT data
cartridge label.

• Create the AIT data cartridge management book. Record the date when each AIT data cartridge
is used and estimate how many years and how often each cartridge is used.

• Examine the AIT data cartridge management book and index label regularly. Discard the
cartridges having low reliability, for example, those which generate write/read errors.

The tape magnetic layer is composed of chemicals and it becomes deteriorated as the time elapses.

Although the tape service life, which is determined by this deterioration, varies greatly depending
on the tape storage environment (humidity, temperature), the tape is generally serviceable for about
3 years since you purchase it.

AIT Data Cartridge 33

Storing Important Data

When storing important data or programs, it is strongly recommended that you should prepare and
store the master tape and copy (backup) tape just in case.

Further, we recommend that you verify backup software when saving, and check saved data. For
details on verification, refer to the instruction manual for the backup software you are using.

By doing this, if one of the tapes causes a read error due to dust or dirt, you can recover the data
from the other tape. Thus, you can prevent loss of important data and programs.

Managing 3-generation Data

To store the data on the disk, you should manage the data in the three generations.
To manage the 3-generation data, use three tapes (A, B, C). On the first day, store the data on the
disk in tape A. On the second day, store the data in tape B. On the third day, store the data in tape
C.

This method allows you to protect your important data. For example, if tape C generates a read
error, you can use tape B to recover the data. If tape B generates a read error, you can use tape A
to recover the data.
