A management unit manages mapping between a continuous series of logical addresses and discrete physical addresses skipping a predetermined number of replacement areas. A controller identifies to which physical address the received logical address is mapped, and controls access to the storage medium using the identified physical address. When a defect occurs in a storage area indicated by a physical address, the information processing apparatus remaps its corresponding logical address to a replacement area adjacent to the defective physical address."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information processing apparatus and access control method","description":"Upon receipt of an instruction to access a logical address of a storage medium, an information processing apparatus controls access to its corresponding physical address of the storage medium.
