METHOD AND DEVICE FOR WRITING DATA IN STORAGE MEDIUM

摘要

The present invention relates to a method and apparatus for writing data to a storage medium, where the method for writing data to a storage medium includes: writing data to a storage unit of a storage medium according to a write cycle of the storage medium, where the storage unit is a read/write unit of the storage medium; after write operations are concurrently executed on n storage units in a first write cycle, counting a quantity k of storage units in which writing succeeds among the n storage units in the first write cycle; and starting, in a second write cycle, write operations on subsequent data whose data amount is m storage units in addition to performing write operations on n-k storage units in which writing is not successful. Statistics about a case in which writing to storage units in the first write cycle succeeds are collected, and when write operations on the k storage units are completed in the first write cycle, write operations on m subsequent storage units are started in the second write cycle, which can improve efficiency in writing data to the storage medium.
