Latest Patents
Ok K Cho holds a patent for an organic-optic recording tape that boasts higher capacity and packing density for data storage. This advanced tape consists of a backcoating layer, a base film, and a complex functional layer designed for writing, reading, and erasing data. The complex functional layer is uniquely coated on the base film and is selectively focused by laser beams of varying powers emitted from a laser diode. This innovative approach allows for efficient data management, including writing, reading, and erasing processes. The complex functional layer is composed of a block polymer created by blending a thermoplastic elastomer with a viscoelastic transparent thermoplastic high-molecular resin. Near-infrared absorbing organic colorants are integrated into this layer, enhancing its functionality. The recording process utilizes a lower power laser beam to induce thermal expansion, while erasing is achieved with a higher power laser beam that induces viscousness in the resin. Reading is performed using a very low power laser beam to create a reflectivity difference between the bump and the normal part of the complex functional layer.
