PURPOSE:To provide the optical floppy disk with an optical head part which is a simple and light weight construction and which can construct an optical disk memory system at a low cost. CONSTITUTION:The optical head 5 is provided with a projected part with a specified curvature formed with a multiple number of slots and at least one piece of a semiconductive laser chip in this projected part. This optical head 5 is faced to the optical floppy disk 3 in a state with a minute gap retained by air bearing effect due to Bernoulli gap formed along with rotation of the optical floppy disk 3. |
