System and method to manage disk write buffer

Abstract

An information processing apparatus includes a nonvolatile memory and circuitry. The nonvolatile memory stores data written using shingled magnetic recording, in which tracks are partially arranged one over another in a radial direction. The circuitry is to instruct the nonvolatile memory to write the data in units of sectors, additionally write the data to a data writing area of the nonvolatile memory, create, on a volatile memory, a buffer for delayed writing in which the data to be written to the data writing area is temporarily held, and write the data in the buffer for delayed writing to the nonvolatile memory in a case that a total amount of data accumulated in the buffer for delayed writing exceeds a threshold value.
