While solid state flash memory has superior mechanical durability, it suffers from a limited number of write cycles unlike HDDs, which allow unlimited writing and rewriting of data. Large capacities are where HDDs continue to have significant price advantage over flash memory. Wikimedia Commons has media related to ZX Microdrive. Ino-san directed a few members of his team to develop working prototypes in collaboration with Research, and used the prototypes to help persuade the IBM HDD product planning and marketing teams to join him in supporting the project. Its HDD-like host interface also made it a natural choice for the Microdrive.

Microdrive is a registered trademark for miniature, 1-inch hard disks produced by IBM and Hitachi. Enabling Technologies The technical success of the Microdrive was built upon optimal miniaturization of conventional components.

Lack of comparable overhead meant that flash memory could scale down to small capacity points at much lower cost than a 1 inch HDD, and thereby always commanded the majority of the micgodrive share at small capacities. Prairie Tek certainly had ramp load for a rotary before IBM but the latter starts playing semantics with “large player”.


Hard disk drives IBM storage devices introductions.

Although 1 inch HDDs only captured a small fraction of the storage business for cameras, this market was vital to the launch of the Microdrive as a product. In short, the 1GB microdrive’s capacity, and the cost for it, are unmatched. Discussion Key players Several IBM employees played key roles in the microdrivf and business development of the Microdrive.

The original MB is by no means a flawless performer, though for every photojournalist that has experienced serious Microdrive problems there seems to be another for whom it has been smooth sailing.

Cost and capacity are not the only measure by which a card should be selected of course. This standard defined the 5 mm thickness needed for an HDD, and a new functional specification called CF Plus, with the needed power supply and command infrastructure to support the HDDs and other non-storage devices that were adopting the CF standard as well.

Contemporaneous market forecasts for the 1-inch form factor were minimal and it was not clear that the form would survive. There was one major problem; although the CompactFlash form factor was among the largest for removable storage cards used in cameras, its 3. By using this site, you agree to the Terms of Use and Privacy Policy. The read speed of the fastest CompactFlash card, the Lexar Media MB 10x, is shown for microvrive in the table below: Changes made on June 20,were discussed by the Storage SIG and agreed upon in concept but not in specifics.


Statements consisting only of original micrkdrive should be removed. A micdodrive efficient pulsed capacitive retract system was developed to perform this function in the Microdrive.

Microdrive relationship to MP3 Players. The release of similar drives by other makers led to them often being referred to as “microdrives” too. Mjcrodrive and Cornice had 12GB models announced in early Apple introduced its first iPod using a Toshiba 1.

One of the main reasons was compatibility with the CF standard. Not to be reproduced without written permission. Seagate also sold a standalone consumer product based on these drives with a product known as the Pocket Hard Drive. As of Julythere are no known manufacturers of 1-inch form-factor harddisk drives.
