Brand: Sony

The Sony CFS-203 is a 3-speed (1000, 1200, and 1500 RPM) form factor compact floppy (1.2 MB) disk drive. It was designed for use in desktop and mobile computers and prioritized compactness and low power consumption. The CFS-203 employed ±10% linear voice coil (LVC) technology to control the disk's spinning speed and reduce power consumption during idle mode. Its connectivity options include a 34-pin mini DIN interface and an RS-232 serial port for communication with the host system. Additionally, it supported both MFM and RLL encoding/decoding schemes for increasing storage capacity and reliability. Overall, the Sony CFS-203 was a popular choice in the 1990s for its performance, reliability, and compact design.
