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.
