History of the Hard Disk Drive:

The following is a timeline of the hard disk drive's history from 1956 to 2007. Different versions of this timeline exist. They are all generally accurate.

1956: IBM ships the first hard drive, the RAMAC 305, which holds 5MB of data at $10,000 a megabyte. It is as big as two refrigerators and uses 50 24-inch platters. (For the full story and interviews with key players, read "The Hard Drive Turns 50")

1961: IBM invents heads for disk drives that "fly" on a cushion of air or on "air bearings." This becomes the standard for all disk drives.

1963: IBM comes up with the first removable hard drive which has six 14-inch platters and holds 2.6MB. It is known as the model 1311.

1966: IBM introduces the first drive using a wound-coil ferrite recording head.

1970: Pertec Computer Corporation (PCC), formerly Peripheral Equipment Corporation (PEC) was founded. This was a computer company based in Chatsworth, California that manufactured disk and tape drives. It's PERTEC disk interface was an industry standard for pre-winchester disk drives of 1970s.

1970: General Digital Corporation (renamed Western Digital Corp. in 1971) is founded in California.

1973: The first modern "Winchester" hard drive, which has a sealed assembly, lubricated spindles, and low-mass heads, is announced by IBM. It is known as the Model 3340.

1975: : Pertec Computer Corporation starts manufacturing the D3000 series 14 front- and top-loading disk drives with capacities of 5mb, 10mb and 20mb.

1979: Al Shugart the founder of Shugat Associates founds disk-drive manufacturer Seagate Technology with a group of engineers.

1979: Seagate introduces the ST-506 drive and interface, which is then used in all early microcomputer implementations. The ST506 had a capacity of 5mb.

1980: IBM introduces the first gigabyte hard drive. It is the size of a refrigerator, weighs about 550 pounds, and costs $40,000.

1981: Shugart Associates joins NCR to develop an intelligent disk drive interface called the Shugart Associates Systems Interface (SASI), a predecessor to SCSI (Small Computer System Interface).

1982: Western Digital announces the first single-chip Winchester hard drive controller (WD1010) which helps it to become the dominate hard drive controller manufacturer 2 years later.

1983: Rodime releases the first 3.5-inch hard drive; the RO352 includes two platters and stores 10MB.

1984: Western Digital makes the first Winchester hard drive controller card for the IBM PC/AT--and sets an industry standard.

1985: Control Data, Compaq Computer, and Western Digital collaborate to develop the 40-pin IDE interface. IDE stands for Intelligent Drive Electronics, more commonly known as Integrated Drive Electronics.

1985: Western Digital produces the first ESDI (Enhanced Small Device Interface) controller board, which allows larger capacity and faster hard drives to be used in PCs.

1986: The official SCSI spec is released; Apple Computer's Mac Plus is one of the first computers to use it.

1988: Connor introduces the first 1-inch-high 3.5-inch hard drive, which is still the common form factor. Before this, hard drives were either full height or half-height.

1988: Western Digital buys the disk-drive assets of Tandon Corporation with an eye to manufacturing IDE drives.

1990: Western Digital introduces its first 3.5-inch Caviar IDE hard drive.

1991: IBM introduces the 0663 Corsair, the first disk drive with thin film magnetoresistive (MR) heads. It has eight 3.5-inch platters and stores 1GB. (The MR head was first introduced on an IBM tape drive in 1984.)

1991: Integral Peripherals' 1820 Mustang uses one 1.8-inch platter to store 21MB.

1992: Seagate is first to market with a 7200-revolutions-per-minute hard drive, the 2.1GB Barracuda.

1994: Western Digital develops Enhanced IDE, an improved hard drive interface that breaks the 528MB-throughput barrier. EIDE also allows for attachment of optical and tape drives.

1996: IBM stores 1 billion bits per square inch on a platter.

1996: Seagate introduces its Cheetah family, the first 10,000-rpm hard drives.

1997: IBM introduces the first drive using giant magneto resistive (GMR) heads, the 16.8GB Deskstar 16GP Titan, which stores 16.8GB on five 3.5-inch platters.

1998: IBM announces its Microdrive , the smallest hard drive to date. It fits 340MB on a single 1-inch platter.

2000: Maxtor buys competitor Quantum's hard drive business. At the time, Quantum is the number-two drive maker, behind Seagate; this acquisition makes Maxtor the world's largest hard drive manufacturer.

2000: Seagate produces the first 15,000-rpm hard drive, the Cheetah X15.

2002: Seagate scores another first with the Barracuda ATA V Serial ATA hard drive.

2002: Among its many 2002 technology accomplishments, Seagate successfully demos Heat-Assisted Magnetic Recording. HAMR records magnetically using laser-thermal assistance and ultimately aims to increase areal density by more than 100 times over 2002 levels.

2003: IBM sells its Data Storage Division to Hitachi, ending its involvement in developing and marketing disk drive technology.

2003: Western Digital introduces the first 10,000-rpm SATA hard drive, the 37GB Raptor, which is designed for the enterprise, but which gamers quickly learn is a hot desktop performer in dual-drive RAID setups.

2004: The first 0.85-inch hard drive, Toshiba's MK2001MTN, debuts. It stores 2GB on a single platter.

2005: Toshiba introduces its MK4007 GAL, which stores 40GB on one 1.8-inch platter, fielding the first hard drive using perpendicular magnetic recording.

2005: Seagate announces the $1.9 billion acquisition of rival HDD firm Maxtor.

2006: Seagate's Momentus 5400.3 notebook hard drive is the first 2.5-inch model to use perpendicular magnetic recording, which boosts its capacity up to 160GB.

2006: Seagate releases a 750GB hard disk, the first 3.5" consumer hard disk to utilize perpendicular recording.

2006: Western Digital launches its 10,000-rpm Raptor X SATA hard drive, boosting its capacity to 150GB and placing a flashy transparent window that allows specially designed computer cases to showcase its inner workings.

2006: Seagate announces a 1-inch hard drive that holds 12GB. The drives are slated to ship in the third quarter of 2006.

2006: Alan Shugart, co-founder of Seagate Technology, dies at the age of 76, several weeks after undergoing open-heart surgery.

2007: In January of 2007 Seagate announced the world's first real 1TB hard disk drive.

NEVER KNOW THAT! Thanx for sharing such a nice article!
People told me that there were some iPod recovery software that could recover data you deleted, lost on iPod. Here is such an iPod data recovery software available.
