Information processing device and method, recording medium, and program

An information processing device comprising:

• a plurality of access processing units configured to record or reproduce data by performing an access control to a recording medium in which sequential recording areas are divided into a plurality of simulated zones in a predetermined size and addresses are set for the respective areas of the simulated zones so that a set of the plurality of simulated zones composes a simulated zone group and the addresses are interleaved between the plurality of simulated zones composing the simulated zone group;
• and
• a control unit configured to control the plurality of the access processing units so that accesses to the recording medium according to the control by the plurality of access processing units are performed at the same time.

An information processing method comprising the steps of:

• by a plurality of access processing units, recording or reproducing data by performing an access control to a recording medium in which sequential recording areas are divided into a plurality of simulated zones in a predetermined size and addresses are set for the respective areas of the simulated zones so that a set of the plurality of simulated zones composes a simulated zone group and the addresses are interleaved between the plurality of simulated zones composing the simulated zone group;
• and
• controlling the plurality of the access processing units so that accesses to the recording medium according to the control by the plurality of access processing units are performed at the same time.

A program that causes a computer to execute a process comprising the steps of:

• by a plurality of access processing units, recording or reproducing data by performing an access control to a recording medium in which sequential recording areas are divided into a plurality of simulated zones in a predetermined size and addresses are set for the respective areas of the simulated zones so that a set of the plurality of simulated zones composes a simulated zone group and the addresses are interleaved between the plurality of simulated zones composing the simulated zone group;
• and
• controlling the plurality of the access processing units so that accesses to the recording medium according to the control by the plurality of access processing units are performed at the same time.
