See TIP > Tape Drive Cleaning Strategies
The TR-3 Tape Unit is a Magnetic-Influence sensitive-Device
therefore the tape unit should be positioned as far as possible away from CD-ROMs, Hard-Disk Drives and/or
Display Units.
Tape Capacity
The formatted capacity of a TR-3 tape will be about 1.6GB. Compressing raw data by a 2:1 ratio
(compression ratios depends on data type) allows to store up to 3.2GB of raw data.

Preformatted Tapes Some types of cartridges are available as formatted or unformatted. Where possible, IBM recommends
pre-formatted tape minicartridges.
Unformatted Tapes Unformatted TR-3 tape minicartridges must be formatted by the drive. Because the
drive is formatting the equivalent of several hundred diskette disks, formatting can take up to six hours.
Flexible Formatting The backup software supports Flexible Formatting standards and will autom. detect the length of the tape in a minicartridge.
The tape is then formatted to its maximum allowable capacity.
Reformatting Tapes Old tapes and tapes that are generating too many errors should be bulk-erased and then reformatted using the software format options.
Erasing tapes with a commercial-grade bulk eraser is the best way to ensure that the tape is ready for reformatting. Commercial-grade bulk erasers are available at
computer dealers.

Cleaning the Read/Write Head
QIC-80 cleaning catridges are NOT compatible with QIC-3020 drives and will damage the
read/write head.
After every 25 hours of operation (appr. 20 backup and or restore), clean the read/write head of the drive using any Dry-Process Cleaning Cartridge that meets the
QIC-147 recognition specifications for QIC-3020 tape drives. Follow the instructions included with the cleaning cartridge.
Operating Temperature and Condensation
Let the drive and any tape minicartridge adjust to operating temperature (from 10° to 45°C or 50° to 113°F) before use. Do not operate the drive when
condensation is present on the drive or tapes.
