Page 11: Introduction To The Drive
3/6 MByte/sec 8/16-bit SCSI SE/LVD ALRF-2 The Tandberg SLR product line is equipped with SCSI interface and supports a variety of data transfer rates. The product is also designed to support older media types according to the table below. The SLR drives read (R) and write (W) according to the following table:... - Page 12 The bezel is equipped with an eject button and three LEDs for drive status information. The front parts include a top-hinged door that will close after the cartridge is loaded, and open inwards when the cartridge is ejected. Figure 2.1 illustrates the Tandberg SLR Drive’s mechanical outline.

Page 46: Important Slr7/60/75/100/140 Recommendation
The SLR140 Drive is optimized for the ALRF-6 format, while the SLR60, SLR75 and SLR100 Drives are optimized for ALRF-1, and the SLR7 drive is optimized for ALRF-2. It is recommended that these media are used even when recording data sets requiring less than the maximum capacity provided by the drives and tapes. -
Page 47: Write Mode
• Before using a new cartridge for the first time a complete retension operation is recommended (tape run from BOT to EOT and back - duration up to 7 min depending on tape length).

If in doubt, always let a cartridge “dry out” outside the packaging box in a normal humidity en- vironment (< 50-65 % rel. hum. at +20°C) for at least 3-4 days prior to use.

The parameters measured are checked against user defined or default limits. In addition the status of the three sensors (Cartridge Present, Write Protect 1 & 2) are checked. The test focus is on motor/mechanical problems forcing operation out of specification. Tandberg SLR Reference Manual 10-15... -

The Head should also be immediately cleaned if “hard” Read or Write errors occur. Use only certified quality cartridges for the Tandberg SLR Product Line Drives. Do not use worn or audibly noisy cartridges. Cartridges which repeatedly require rewriting of large numbers of blocks per track should also be rejected. - Page 110 Tandberg Data Preventive Maintenance ___________________________________________________________________________ This Page Intentionally Left Blank 11-2 Tandberg SLR Reference Manual...

Page 115: App. C. Led-Indicator Behavior
When a diagnostic activity leads to media operations (load/eject, read/write etc.) the LED behaviour changes to a behaviour that corresponds to this kind of operation in a normal activity. This is not valid for LED-behavior during Standalone Diagnostics started from Service Mode. This behavior is described in Section 10.5 Tandberg SLR Reference Manual... -
