Drive Speed Page
The speed field provides a means for the initiator to set and retrieve the spindle speed
when accessing data areas.  The speed field values are listed in Table 2-9-8A on the
opposite page.
The speed setting is only applicable when reading data areas.  The target will
automatically switch to normal speed when playing audio tracks and will switch back
to the speed setting when accessing data.
DRIVE NOTES:
DRM-602x
The DRM-602x does not support 4x speed.  A speed setting value of 03h
will not cause an error,  but set the drive to 2x speed.
DRM-624x, DRM-604X, DR-U124X, DR-UA124X, DR-D504X
These drives do not support 2x Speed.  A speed setting value of 01h will not
cause an error.
However,  the drive will automatically be set to 4x speed.
