Abstract
The magnetic bubble memory has advantages in regard to nonvolatility and high reliability originating from its no moving parts structure. The bubble me mory has been applied so far in a defined field such as data terminal, voice announcement system and elec tronic switching system, where these advantages are essential. Recently, bubble memory boards have been placed on the market aiming at extension to the data processing field. Subjects for a future effort are further improvement in chip integration and significant in crease in market size, because the bubble memory is rather more expensive than large scale MOS RAM and floppy disk. Device standardization and LSI support circuits would be additionally required for market improvement.
