A method and system for writing data which includes the steps of: receiving a write command, storing associated data in a buffer memory, determining whether or not enough free space exists in the buffer memory to store a subsequent unit of write data, and sending a "command complete" signal to the external device, if it is determined that there exists enough free space to store a subsequent unit of write data. The disk drive unit includes: a random access recording medium, a command memory, a buffer memory, and a logic circuit for determining whether or not enough free space exists in the buffer memory to store a subsequent unit of write data, with a predetermined reference value representing the amount of free space occupied by a typical unit of write data.
