SCSI Interfaces
Ultra160 (160MBs)
Eight devices can each send/receive 20 MB of data per second
Ultra2 (80MBs)
Four devices can each send/receive 20 MB of data per second
Wide Ultra (20MBs)
Only one device can send/receive 20 MB of data per second
SLR140 burst transfer rate of 40 MBs, supporting both LVD and SE interfaces gives
improved overall system performance.

9. SLR140 Features to Assure Compatibility and Scalability
Four write-channel TFMR Head
The Tandberg SLR60-140 features a thin-film, inductive write/magneto-resistive read head with five
dual channels, and an additional dual channel for the SLR24, SLR32, SLR50 formats. The magnetic
elements are all small elements that for the write operation can magnetize the particles on the media
with a low write current.
dual channels, and an additional dual channel for the SLR24, SLR32, SLR50 formats. The magnetic
elements are all small elements that for the write operation can magnetize the particles on the media
with a low write current.
Of the five dual channels for the SLR140 format, one is used for reading the servo track while the other
four tracks are used for parallel writing and reading. Each of the dual channels accommodates two
combined read/write elements. When the tape media is moved in forward direction the first element
acts as a write element, and the other as a read element for the read-while-write operation.

acts as a write element, and the other as a read element for the read-while-write operation.
When the tape media is moving in the reverse direction, the other element - which was the read element
in forward direction now - acts as the write element. The read-while-write operation is then performed
by the last element, which was the write element in the forward direction.

With, this head technology adding more channels for higher future higher capacity and higher transfer
