The SP-12 requires double-sided, double-density, 48 tracks per inch (TPI) 5.25”
floppy disks. Cassettes should be high-quality data cassettes, not standard audio
cassettes.
Disk drives are somewhat fragile. Before transporting the 1541 (even if it’s only
across the room), always insert and latch either the original packing material or a
“scrap” disk into the drive. This protects the drive from vibration. Do not use a good
disk, as it could become damaged during transit.
When active, the Drive’s red LED will light. Do not try to operate any controls when
the LED is on (why tempt fate?). The mechanism will occasionally make whirring and
“clunking” sounds; these are normal.
Labeling
Labelling your disks and cassettes will save frustration; keep a log of where data is
saved. With disks, write on an adhesive label that you then attach to the disk. Writing
on the disk can damage it; but if you’re the gambling type, at least use a felt- tip pen
and apply very little pressure.
Write-protecting disks and cassettes
Write-protecting a disk turns off the disk drive’s ability to record on to the disk, thus
preventing accidental erasure. To write-protect a disk, fold a small adhesive tab
(usually supplied with the disk) over both sides of the disk so that the write- protect
notch (see Fig. 5-1) is completely covered (see Fig. 5-2). As long as the notch is
covered, you will not be able to accidentally record over the disk. If you try to write on
a disk and cannot, check whether it is write-protected before proceeding.
