The ZX Spectrum Beta Disc 3.5" floppy is the 3 1/2" disk format used with ZX Spectrum computers, with the TR-DOS filesystem.
5¼" and 3½" floppies are used with the following formats (sources are unclear as to which of these formats are used with each of the sizes):
| Number of tracks per side | Number of sides | Number of tracks (total) | Number of sectors | Number of bytes |
|---|---|---|---|---|
| 80 | 2 | 160 | 2560 | 655360 |
| 40 | 2 | 80 | 1280 | 327680 |
| 80 | 1 | 80 | 1280 | 327680 |
| 40 | 1 | 40 | 640 | 163840 |
Diskettes can be dumped to TRD files for use in emulators.
