Modular Design

Data Control Module 1 The Data Control Module (DCM) contains several of the functions and

features of LGMR technology, which is at the heart of the SDLT

technology. Of the five technologies that constitute the LGMR

technology, two are in the DCM. These are the POS and the MRC heads.

The main functions of the DCM are to provide the path and guides for all

tape motion inside the tape drive and to write data to and read data from

the tape. In addition to the POS and MRC heads described in Pivoting

Optical Servo and Magneto Resistive Cluster Heads, the DCM contains a

number of components that interact to perform these functions. These

components include:

• Advanced head guide assembly

• Take-up reel

•Drive motor

• Optical servo system

Note: 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.
