Track The Logical Track Number the heads are on at the time of the event. The
DLT tape drive is a linear recording device with multiple tracks. The
Read/Write Head Assembly has more than one head so that multiple
physical tracks of data are read or written at the same time. These
multiple tracks are referred to a one logical track.
Physical Block
Number on Track
A physical location on the media based on distance from the end-of-track
depending on which direction the tape is moving. Tape moving from
Beginning of Tape (BOT) side of tape to End of Tape (EOT) side is
distance from BOT. In the opposite direction, it is the location from the
EOT side of the tape. This data, with the track number, can be used to
help identify if repeated failures always occur at the same spot, meaning
data written wrong, or bad spot on media.
