Smaller diameter media came into usage during the 1970s and by the end of the decade standard form factors had been established for drives using nominally 8-inch media (e.g., Shugart SA1000) and nominally 5.25-inch media (e.g., Seagate ST-506). The word fixed is used because the drives are internal or in an enclosure thats not easily removed. Omissions? A fixed disk may also refer to the disk platter inside of a hard drive.
