v

The tape (see item

) was wound completely out of the cartridge (see

 

item

) onto the machine reel (not shown). It was then reattached to the

 

cartridge reel (not shown) by the service representative. This repair is

 

temporary and permits the cartridge to be loaded one time. This allows the

 

data to be copied to a replacement cartridge.

v

The file-protect selector (see item

) is damaged.

vThe braking mechanism (not shown) is jammed or broken.

vThe cartridge has other obvious damage.

Cartridge Quality and Library Maintenance

The IBM tape cartridge provides high performance and reliability with IBM magnetic tape cartridge drives when the cartridge is properly handled and stored. As discussed previously, repeated handling or inadvertent mishandling can damage the physical parts of the cartridge and make it unusable.

The magnetic tape inside the cartridge is made of highly durable materials. However, the tape wears after repeated cycles in the tape subsystem. Eventually, such wear can cause an increase in tape errors.

Track the error data available by monitoring both the cartridge and cartridge library performance. By monitoring error data, you can identify and replace cartridges that are no longer acceptable for continued use.

Proper maintenance of your cartridge library helps to keep IBM magnetic tape cartridge systems operating in a reliable and efficient manner.
