The Sony MP-F17W-12 is a 3.5-inch internal floppy disk drive engineered for PC systems requiring legacy data storage and retrieval. This beige unit delivers dual-mode read/write performance at 500 Kbits/sec (1.44 MB mode) and 250 Kbits/sec (720 KB mode), with track-to-track access time of 3 msec and 15 msec settling time. Purpose-built for double-sided high-density (DS HD) disk formats, the drive operates at 300 rpm across 80 cylinders with 135 tpi track density and MFM encoding.
