<p>Created page with &quot;{{FormatInfo |formattype=physical |subcat=Floppy disk |released=1987 }} The &#039;&#039;&#039;Commodore 1581 disk&#039;&#039;&#039; is the native format of the 1581 disk drive, a 3.5&quot; disk drive released ...&quot;</p> <p><b>New page</b></p><div>{{FormatInfo<br /> |formattype=physical<br /> |subcat=Floppy disk<br /> |released=1987<br /> }}<br /> <br /> The '''Commodore 1581 disk''' is the native format of the 1581 disk drive, a 3.5&quot; disk drive released by Commodore for its Commodore 64 and 128 computers.<br /> <br /> The 1581 disk has 80 logical tracks with 40 logical sectors in each, totalling 3200 sectors, each of which held 256 bytes. This led to a total storage capacity of 800 kilobytes. The physical structure of the disk was abstracted away by the on-board logic, presenting sequentially-numbered logical tracks and sectors to the operating system.<br /> <br /> A variant of [[CBMFS]] was used for the filesystem; see [[Commodore 1581 filesystem]].<br /> <br /> The prototype Commodore 65 computer used this type of disk.<br /> <br /> The low-level format was similar enough to the [[PC-DOS 720K disk]] format to allow software-based emulation and data transfer between the two platforms.<br /> <br /> == Links ==<br /> * [[Wikipedia:Commodore 1581|Wikipedia article]]<br /> * [[Wikipedia:Commodore 65|Commodore 65 (Wikipedia)]]<br /> <br /> [[Category:Commodore computers]]</div>
