Chapter 1 Tape Drive Product Information Tape Drive Technology 1 Pivoting Optical Servo (POS) is a Quantum-invented, optically-encoded Pivoting Optical Servo servo system, that combines high-density magnetic read/write data recording with laser servo guiding. The POS provides high-duty-cycle applications, which decreases cost and increases user convenience.
Chapter 1 Tape Drive Product Information Modular Design extensive duty-cycle environments found in high-end and automation environments. This mechanism engages the tape leader upon data cartridge load and disengages it upon data cartridge unload. It uses a solid metal pin attached to the drive leader to link with molded clips permanently attached to the tape leader inside the data cartridge. The Positive Leader Link design makes the buckling of Super DLTtape media a totally reliable mechanical process.
Chapter 1 Tape Drive Product Information Modular Design Figure 2 SDLT 600 Tape Drive Modular Design TCM FPM Data Cartridge DCM EIM ICM EIM HIM Note: Data Control Module Despite the deliberate modularity of each module, with the exception of the FPM, individual users should not swap modules. The FPM is the only module that is field replaceable. Customer adjustments to the TCM, DCM, or EIM will void the tape drive’s warranty.
Chapter 1 Tape Drive Product Information Modular Design • Tape heads. In addition to its mechanical components, the DCM also contains printed circuit boards that control the functions of the DCM and the tape heads. Tape Control Module 1 The Tape Control Module (TCM) implements the functions required to buckle and unbuckle the tape and control the tape motion.
Chapter 1 Tape Drive Product Information Modular Design Data Cartridge Receiver 1 On tape insertion, the data cartridge receiver assembly guides the tape into its operating position, opens the data cartridge door, unlocks the data cartridge brakes, engages the data cartridge drive motor, and secures the tape for operation. On tape ejection, the data cartridge receiver assembly reverses the process and automatically ejects the tape a fixed distance from the front of the tape drive.
Chapter 1 Tape Drive Product Information Quantum Diagnostics Tools The EIM consists of two major boards: the Integrated Controller Module (ICM), and a separate Host Interface Module (HIM). The ICM contains the main controller and servo microprocessor, the custom-designed SDLT ASICs, and the cache memory while the HIM implements the interface between the host system and the tape drive.

Chapter 4 4 Using Your Tape Drive This chapter describes how to start using your SDLT 600 tape drive system. This includes making a trial back-up, cleaning the tape mechanism, and various troubleshooting information. This chapter also includes information on the LEDs and buttons on the front panel of the system. This chapter covers the following topics: SDLT 600 Product Manual • Power-On Self-Test describes the sequence of activities that occur when power is first applied to the tape drive.
Chapter 4 Using Your Tape Drive Power-On Self-Test Power-On Self-Test 4 The SDLT 600 tape drive system performs a Power-On Self-Test (POST) each time the tape drive is powered on. POST normally completes in 10 to 15 seconds—when a data cartridge is not in the tape drive— when the unit is powered on. However, if a data cartridge is in the tape drive when the unit is powered on, POST duration is longer, depending on how much tape in the data cartridge may be loaded in the tape drive.
Chapter 4 Using Your Tape Drive Performing a Trial Back-up Stage Note: What You Observe If a data cartridge is in place when power is turned on, all stages remain the same except stage 3. It may take a considerably longer time for stage 3 to complete due to tape rewind and searching operations that occur during that stage.
Chapter 4 Using Your Tape Drive Updating the Firmware • If you experience errors, doublecheck the tape drive’s configuration and setup, using the ideas provided in Troubleshooting on page 80. • After you have exhausted all troubleshooting alternatives, contact your service representative. • Press the Eject button to unload the data cartridge.
