(3) The write-protect sensor disables the Diskette Drive electronics whenever a write-protect tab is applied to the diskette. For Interface Information, refer to the Diskette Drive Adapter section. ~ Diskettes The <strong>IBM</strong> 5-1/4" Diskette Drive uses a standard 133.4 mm (5.25 in.) diskette. For programming considerations, single sided, double density soft sectored diskettes are used. The figure below is a simplified drawing of the diskette used with the Diskette Drive. This recording medium is a flexible magnetic disk enclosed in a protective jacket. The protected disk, free to rotate within the jacket, is continuously cleaned by the soft fabric lining of the jacket during normal operation. Read/Write erase head access is made through an opening in the jacket. Openings for the drive hub and diskette index hole are also provided. _____ m 11-- 3.S6 mm (D.140 INCH) 630 + 0.25 mm 133.4 mm I - I~Fr{025+ 0.01 INCH) j- (5.251NCH) I 1 ~~~~~~TlVE~ /' -- - - ---- "-..
