Embodiment Construction

[0049] Now, embodiments of the present invention will be described in detail, examples of which will be illustrated in the accompanying drawings, in which like reference numerals refer to like parts throughout. The embodiments below will be described in order to explain the present invention by referring to the figures.

[0050] According to an aspect of the present invention, there is provided a method of distinguishing an R zone by giving a flag including priority information to a command for reserving an R zone as a reserve track command. That is to say, in the embodiment of the present invention, there is provided a command to add priority information except the size information of the reserved R area to the reserved R area as an input parameter to the reserved area, thereby indicating that the R area method of priority.

Abstract

An information storage medium, a recording / reproducing apparatus using the information storage medium, and a recording / reproducing method using the information storage medium. The information storage medium includes a data area in which replacement information is managed for data replacement due to a defect in recorded data or data replacement by logical overlay (LOW) due to update of data. The data area of ​​the medium includes more than one R zone, and a priority attribute is given to each R zone, so that data to be recorded in the medium can be recorded in each R zone based on the priority of the data . Therefore, by dividing the user data area of ​​the medium into a plurality of R areas and writing data into each R area according to the attribute of the data to be recorded, the user data area of ​​the medium can be used according to the instruction of the host, thus improving the efficiency of media usage.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2004-0090160 filed in the Korean Intellectual Property Office on Nov. 6, 2004, which is hereby incorporated by reference. technical field [0002] The present invention relates to the field of discs, and more particularly, to an information storage medium supporting defect management of a user data area, a recording / reproducing device using the information storage medium, a recording / reproducing device using the information storage medium Method and host using the information storage medium. Background technique [0003] In a rewritable information storage medium, a spare area is usually prepared in a part of the data area. Therefore, if a defect is detected when user data is recorded in the user data area (area obtained by excluding the spare area from the data area) or when data recorded in the user data area is being reproduced, the Replacement d...
