You re-use the disc space of deleted files (like you do with a floppy or harddisk) or erase the complete disc. Note, the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJAempwpEbGdrcN5Y29ycA" class="cyc_term">CD_R</a> contains CompactDiscs that are only `Writeable Once'.

A disjoint collection type is such that its instances are collections that are all disjoint from one another.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvubaMZwpEbGdrcN5Y29ycA" class="cyc_term">ConventionalClassificationType</a> is a collection that corresponds to a category in some agreed-upon or conventional classification system (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwNgIyZwpEbGdrcN5Y29ycA" class="cyc_term">ClassificationSystem</a>) used by people. In such systems, a change or reclassification is possible by a decision of an authority, or by a changed social agreement or custom, without changing the intrinsic natures of the actual objects in the category. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvubaMZwpEbGdrcN5Y29ycA" class="cyc_term">ConventionalClassificationType</a>s include categories in biological taxonomy, standard classifications in data dictionaries and thesauri, cultural taboo classes, military doctrinal classes, and named calendar intervals.
