Abstract:
1. A method of writing data on a recording medium, in response to a write request issued from an external device, comprising the steps of: receiving a write command; storing write data corresponding to said write command in a buffer memory; checking a first condition that determines whether or not a free space of said buffer memory is larger than a predetermined reference value, which is greater than a memory space equivalent to a unit of said write data; checking a second condition that compares a logical block address of a preceding write command with a logical block address of said write command to ascertain whether or not a position of said logical block address of said write command overlaps a position of said logical block address of said preceding write command; and returning a command complete signal to said external device in response to said write command if either said first condition or said second condition is satisfied.
