On June 1, 1978, Apple launched the Disk II floppy drive, addressing the Apple II computer's lack of storage and setting the stage for high-profit margins.
The Disk II provided a better storage solution compared to cassette tapes, with IBM shrinking the 8-inch floppy disk to 5 1/4 inches, making it cutting-edge for personal computers at the time.
Apple co-founder Steve Wozniak built the disk drive following a recommendation from Mike Markkula to make the Apple II more appealing by improving storage access.
The Disk II's launch in June 1978 boosted Apple II sales, marked significant profitability for Apple, and signaled a shift towards a more committee-driven approach to tech development at the company.
