Abstract:
1. A data recording/reproducing system for recording and reading out data, said data recording/reproducing system comprising: a first storage device using a rotating disk; and a second storage device using a semiconductor memory: wherein, when a file is recorded in said data recording/reproducing system, the entirety of the file is stored into said first storage device and a starting section of the file is stored into said second storage device, and file readout from said data recording/reproducing system is conducted by first reading out all the starting section of the file from the second storage device and then reading out remaining sections of the file directly from the first storage device, wherein: after the start of readout of a starting section of the file from said second storage device, when a readout length of time required for readout of all a remaining unread part of the starting section from the second storage device at an equimultiple speed, is longer than a starting length of time required to make reproduction possible with the first storage device when starting from a non-rotational state, a starting process for initiating activation of the first storage device to begin to make reproduction possible is not performed.
