Course description and aims

Various big data, being stored in the information storage, can be analysed and used to provide solutions for solving social issues and values through ICT (information and communication technology) and electronics technology which support human intellectual creativity. The age of IoT (Internet of Things) and digital society has come. As services grow from things to events, and value to digital society is becoming an important factor alongside economic value. Business and society is being dramatically changed and we need to reconsider what issues to address.
This course focuses on the information storage technologies supporting IoT and digital society. Topics include the read/write operation principle and the head and medium technologies in the magnetic disk and tape recording, the optical recording (eg, the magneto-optical, the phase-change, and the organic dye optical recording) technologies, and the storage systems such as the disk array. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of information storage technologies and industries, the research and development systems in companies, and the literacy necessary for global human resources who can succeed in the world.

Student learning outcomes

By the end of this course, students will be able to understand:
1) the information storage technologies supporting IoT and digital society.
2) the read/write operation principle and the head and medium technologies in the magnetic disk and tape recording,
3) the optical recording (eg, the magneto-optical, the phase-change, and the organic dye optical recording) technologies,
4) the storage systems such as the disk array,
5) the fundamentals of information storage technologies and industries, the research and development systems in companies,
6) the literacy necessary for global human resources who can succeed in the world.

Keywords

information storage, magnetic recording, optical recording(magneto-optical, phase change, organic film, etc), read/write, recording media, recording head, sensor technology, disk array, file memory system

Competencies that will be developed

Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills

Class flow

In each class, the feature of the information storage technology and market will be explained using power point files and prints with actual circumstances of research and development in the global companies, which will be useful to decide on the course to take the career to pursue after graduation. At the beginning of first course, students must to visit an electronics retail store to survey and understand the present situation of storage products such as HDD and SSD. At the end of first course, students must to make presentations on the future of the information storage from the view point of its market and technologies, which will be helpful for students to improve their presentation and communication skills. Students are given the lectures and "task" (Reading and understanding of the related paper, answering to the simple questions) at the end for overall understanding.
