The candidates for data migration destinations, such as ODA and LTO, are long-term storage media. They are relatively resistant to changes in temperature and humidity, highly durable, and are considered to have a longer lifespan compared to common DVD/Blu-ray discs and hard disks. Additionally, many of them have large capacities, making them excellent for long-term storage of large amounts of data. 【Types of Storage Media】 ■HDD ■Long-term storage DVD/Blu-ray ■LTO (Linear Tape-Open) ■ODA (Optical Disc Archive) *For more details, please download the PDF or feel free to contact us.

• Data Backup

Data migration refers to the process of moving data between different formats, software, and devices. New recording media are being developed one after another, aiming for larger capacity and higher durability. Some media require dedicated drives, and due to technological advancements, generations are established, which may limit compatibility for reading and writing across different generations. Considering the characteristics of each media along with the purpose and frequency of data usage, let's consider the migration and rewriting of data (data migration) from older to newer media and across different devices and software. 【What becomes possible】 ■ Longer preservation period ■ Space-saving storage *For more details, please download the PDF or feel free to contact us.

• Data Backup

Audiovisual materials have now become mainstream in data formats that are space-saving and easy to handle on computers, but this "data format" cannot be considered completely reliable for storage. There are various risks that could render the data unusable in the future, such as damage or loss of data due to deterioration of recording media, changes in playback environments, and other factors. To maintain the data stored on recording media in a state that allows for long-term preservation and viewing, we should consider not only the digitization of audiovisual materials but also the methods for data storage and preservation. [Challenges] ■ Risk of damage or failure ■ Media lifespan ■ Decrease in playback devices ■ Intergenerational compatibility ■ Supply duration *For more details, please download the PDF or feel free to contact us.
