Abstract
An information recording/reproducing apparatus is disclosed which includes: a recording section for recording files to a storage medium; an arranging section for arranging the files into groups by attribute so as to establish allocation of the files on the storage medium; and a controlling section for controlling the recording section so as to record the files to the storage medium based on the allocation established by the arranging section and to record concurrently allocation information reflecting the allocation to a predetermined location on the storage medium.

An information recording apparatus comprising:
- a recording section configured to record files to a rotating storage medium, each file including an attribute indicator;
- an arranging section configured to assign, to a first group in a plurality of predetermined groups, each file having an attribute indicator corresponding to the first group, and assign, to a second group, each file having an attribute indicator that does not correspond to any of the plurality of predetermined groups;
- and
- a controlling section configured to control the recording section to
- set up a first partition of the rotating storage medium that a reproducing device can read in a first single pass of the rotating storage medium,
- set up a second partition of the rotating storage medium that the reproducing device can read in a second single pass of the rotating storage medium,
- record, in the first partition, all of the files assigned to the first group so the reproducing device can read all of the files having the attribute indicator corresponding to the first predetermined group in the first single pass of the rotating storage medium, and
- record, in the second partition, all of the files assigned to the second group so the reproducing device can read all of the files having the attribute indicator that does not correspond to any of the predetermined groups in the second single pass of the rotating storage medium.
