Contains the value returned by a
MODE SENSE
command for the density
described in the remainder of the Density Support Data Block Descriptor.
Secondary Density
Code
When multiple density code values are assigned to the same recording
technology, this field lists the equivalent density code value. If no secondary
density code exists, the drive returns the primary device code value in this field.
WrtOK
Write OK. When set to 0, indicates that the drive does not support writing to the
media at this density.
When set to 1, indicates that the drive is capable of writing at this density to
either the currently mounted medium, if the Media bit in the Command Block
Descriptor is set to 1, or to any media, if the Media bit in the Command Block
Descriptor is set to 0. Note that all density code values the
