CHAPTER 11 Input-Output Units
Cleaning the magnetic head
134
 Each data cartridge has an expendable service life. If the Attention LED blinks frequently or
continuously after the magnetic head has been cleaned, the life of the data cartridge has expired.
Generally, replace data cartridges with new ones after they have been used 300 times.
After the DAT unit has been used for a long time, the magnetic head will accumulate dust or
magnetic powder from the tapes. If the magnetic head is left dirty, it may damage a tape, or deposit
dust or magnetic powder onto a tape and thus cause errors or data destruction. Therefore, use a
cleaning cartridge to clean the magnetic head.
Clean the magnetic head when:
 The DAT unit has been operating for more than 25 hours.
 One month has passed since the last head cleaning
 The Attention LED is blinking
 The cleaning instruction message is output to the console display.
When a cleaning cartridge is inserted into the DAT unit in the same way as a data cartridge, head
cleaning will start automatically. Head cleaning takes about 30 seconds. The cleaning cartridge is
ejected automatically after cleaning is completed.
Replacing the cleaning cartridge, when the cleaning cartridge is used, a portion of the cleaning tape
is moved from the left reel to the right reel as shown in the figure above. Each part of the tape is
used once only.
Replace the cleaning cartridge when there is no more tape on the left reel.
IMPORTANT
Do not use any method other than a DDS-approved cleaning cartridge which has a DDS
logo on it.
