Abstract

In an optical storage device the loader mechanism plays an important part in the overall design of the drive and in meeting customer requirements. The loader must be designed to meet lifetime requirements, it must be easy to use, and it must allow for maximum space for the various other components necessary within an optical drive. Today there exists three general loader configurations.

Optical Drive Loader Configuration

      In an optical storage device the loader mechanism plays an
important part in the overall design of the drive and in meeting
customer requirements.  The loader must be designed to meet lifetime
requirements, it must be easy to use, and it must allow for maximum
space for the various other components necessary within an optical
drive.  Today there exists three general loader configurations.

      Figs. 1 and 2 show the loaded and unloaded states of a TYPE A
loader.  The media is inserted horizontally until it is fully within
the drive and is then lowered onto the surface of the spindle motor.
This configuration is pleasing to the user (horizontal loading) and
because the spindle motor is not moved, it offers a stable drive
design.  However, it is not optimum in the space that it provides for
other components nor in the amount of dead space used.

      Figs. 3 and 4 show the loaded and unloaded states of a TYPE B
loader.  A tray is angled upward and the media is inserted.  Then the
tray is lowered down onto the spindle motor.  This design uses much
space.  Here again the spindle is not moved so there is good drive
stability.

      Figs. 5 and 6 show the loaded and unloaded states of a TYPE C
loader.  In this configuration the media is inserted horizontally and
the spindle motor moves during the load/unload operation.  This
moving spindle motor causes drive stability challenges (resonances,
tilt requirements,...
