The IBM 3330 Direct Access Storage Facility, code-named Merlin, was introduced in June 1970 for use with the IBM System/370 and the IBM System 360/195. The original announcement included the 3330 Model 1, with two drives, and the 3330 Model 2, with only one drive.

The IBM 3330 Direct Access Storage Facility, code-named Merlin, was introduced in June 1970 for use with the IBM System/370. Its removable disk packs held 100 MB (404 tracks/surface x 19 surfaces x 13,030 bytes/track). An upgrade in 1972 doubled capacity to 200MB by increasing tracks per inch from 384 to 808.

In 1969, IBM charged San Jose project manager Kenneth E. Haughton with developing a “direct access storage facility” that matched the performance of the high-end IBM 3330 system at a price attractive to low-end System/370 computer customers. The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low ...

The IBM 3830 storage Control and the IBM 3330 Disk storage combine to provide a high capacity direct access storage facility for medium-to-large scale IBM computers. Attached to a block multiplexer channel, each facility provides fast access to as many as 800,000,000 bytes of online storage. standard checking and retry features increase sys­

This brocbure announces the IBM 3330 Model 11 and the IBM 3333 Model 11. It is also an update announcement of the IBM 3333/3330 Disk Subsystem. and 195 and System 1370 Models 135, 145, 155, 158, 165 and 168. The 3830 Model 2 with 3333 Model 11 and 3330 Model 11 are available with System /370 Models 135, 145, 155-11, 158, 165-11 and 168.

The modern solution to this problem was introduced in the IBM 3330 for use with the IBM System/370 in 1970. With the IBM 3330 the head assembly is movable to arbitrary positions by means of a current-carrying coil inside a fixed magnet (coiled a "voice coil" for use of the same effect in loudspeakers (where the magnet moves inside a coil.))

2018年7月24日 · The 3330-1 achieved 100MB via increasing both tracks per inch and the number of bits per track, and the 3330-11 version again doubled the tracks per inch to achieve 200MB. Positioning the heads was based upon information recorded on the lowest disk surface, allowing tracks to be closer together than practical with mechanical detents thereby ...

1970年，ibm推出ibm3330磁盘存储设备。 通过伺服反馈技术（servofeedbacktechnology），IBM3330能在比以前密度更大的磁盘上记录数据。 另外，它还支持纠错码技术，增加了数据的可用性，提高了生产工艺的效率。

Jim Porter: The objective for this discussion is to discuss the products which became known as the IBM 2314, and along the way, the 2319, the 3330, the controllers that went along with all of this and, oh, by the way, the creation of the whole plug compatible disk drive industry that started during all of this with IBM's competitors.
