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 contami-
nated 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.
