Magneto-Optical Disc (MO) driver is an optical disc drive that can write and rewrite data on the magneto-optical disc.Although this technology has been undergoing development since 1983, in recent years, the application of LIMDOW (Direct Overwrite of Light Intensity Modification) technology has brought significant improvements to the performance of this storage medium.This article will explore in-depth how LIMDOW technology works and how it improves the performance of magneto-optical discs.
The history and development of magneto-optical discs
The concept of magneto-optical disc began in 1983 and gave its first experimental report at the 73rd AES conference.In 1985, magneto-optical disc technology was officially commercialized.Although magneto-optical discs were once widely used in some countries (such as Japan), their use gradually decreased with the rise of other storage media.
The earliest 130mm magneto-optical discs look similar to CD-ROMs, using an old-fashioned disc box package to provide dust protection, while the 90mm magneto-optical disc has only a single-sided capacity.These drives operate in a similar way to hard drives, but their technical background is completely different.
How to Work in LIMDOW Technology
LIMDOW technology improves the write speed of early magneto-optical drivers.Compared to traditional magneto-optical drives that require multiple write operations, LIMDOW technology can complete all write processes in a single step.This is because the LIMDOW magneto-optical disc integrates a multi-layer magnetic material. When the laser pulse is heated to a specific temperature, the writing mode will change according to the magnetic properties of the material.
The introduction of this technology has significantly improved the writing performance of magneto-optical discs and enabled its data transmission speed to reach 4 Mbit/s.
Applications and Markets
Although magneto-optical disc technology has been around for decades, it still maintains its value in some specific areas, such as legal document storage and medical image data.This is due to the superior performance of magneto-optical discs in terms of data integrity and reliability.
The magneto-optical disc can check its integrity immediately after writing data, which makes these media more reliable than CD-R or DVD-R.
Future development trends
With the development of new technologies, such as light-induced magnetization and melting, and new data storage methods, the future of magneto-optical discs is still full of unknown possibilities.Although relatively few technologies are used today, their performance cannot be replaced in some professional applications.
As the demand for data storage continues to increase, traditional data storage technology is being replaced by new technologies.Can magneto-optical discs usher in their second spring and become real candidates for the new generation of storage media?
