Achievement of World’s Highest Areal Density on Linear Magnetic Tap
An increase in worldwide data storage volume, forcing the manufacturers in producing larger capacity data storage media. But in order to increase the storage volume of magnetic tape storage media, it is necessary to micrify the particle size and increase the recording density. However, this procedure is extremely cumbersome using metal particle as one of the most popular material among the magnetic tape media market, all due to keeping the high coercivity for high density recording. Based on this challenge, Fujifilm has developed BaFe (Barium Ferrite) particles in achieving the world’s highest areal density of 29.5 billion bits per square inch on linear magnetic tape ,paving the way in manufacturing a 35 terabytes of data capacity per cartridge , 44 times the data capacity of today’s industry magnetic tape product.

Development of world’s highest light output for Organic EL devices by SDK
Showa Denko KK. (SDK) made an announcement on development of a new structure for company’s coated phosphorescent polymer based Organic Electroluminescent devices capable of achieving around 40% in light output. The new device with the 30 lm/W emissive efficiency is the highest level that has been recorded among coated type organic EL devices in the world. The company is hoping for commercialization of this new structure to be used for general lighting application in the future. Under the production process organic EL devices are classified into two types, deposition type and coated type. Unlike the deposition type which has a multilayer structure and requires vacuum for its production at a high cost, the coated type consists of few layers which is formed by coating polymer without the use of vacuum, providing a substantial cost reduction in its production.
