SDLT 600 Product Manual Chapter 3: SDLT 600 Tape Drive Specifications

3.1.9Media Durability

Table 3-8shows the number of media passes and full media uses to expect from a Super DLTtape II data cartridge.

Table 3-8.Super DLTtape II Data Cartridge Media Durability

	Media Durability
Media passes*	1,000,000
Full media uses**	250

*A media pass occurs with any movement (in either direction) of the surface of the media over the tape head.

**A full media use is an operation that reads or writes (with verify off) the full capacity of the data cartridge.

3.1.10 Data Cartridge Life Expectancy

Table 3-9shows the number of load and unload cycles you can expect before the data cartridges need to be replaced.

Table 3-9.Loading and Unloading the Data Cartridge (Maximum)

	Super DLTtape II Data Cartridge
Data cartridge load/unload cycles*	5,000
Media insertions**	20,000

*A load/unload cycle is when a data cartridge is inserted into the receiver, loaded to BOT, calibrated, and then unloaded.

**An insertion is when a data cartridge is inserted into the receiver and then unloaded.

3.1.11 Positive Engagement Tape Leader Buckling Mechanism

This buckling mechanism engages the tape leaders upon data cartridge load and disengages them upon data cartridge unload.

Component level tests of buckle arm components have shown at least 250,000 cycles on an SDLT 600 tape drive without failure, breakage, or binding; this includes the take-up leader, the supply leader, and the media itself.
