## Abstract

A method of designating a disk recording capacity and an optical disk recording apparatus using the method, where a maximum recording capacity is designated by measuring an external disturbance for disk regions. The method of designating a disk recording capacity includes: partitioning a disk into a plurality of disk regions, and measuring external disturbance at the disk regions; setting a disk speed based on the measured external disturbance, and designating disk regions excluding the disk regions where the external disturbance is measured as recordable disk regions; and calculating a maximum disk recording capacity based on the designated recordable disk regions.

## Claims

### Claim 1

A disk recording method, comprising:
partitioning a disk into a plurality of disk regions, and measuring for an external disturbance at each of the disk regions, from an internal circumference to an outer circumference of the disk, and measuring the tilt and eccentric center for each of the disk regions;
setting a disk speed based on the measured external disturbance, and designating disk regions, excluding the disk regions where the external disturbance is measured, as recordable disk regions; and
calculating a maximum disk recording capacity based on the designated recordable disk regions.

### Claim 2 (depends on 1)

The disk recording method according to claim 1, wherein the designating of the disk regions, comprises designating the disk regions as the recordable disk regions, excluding the disk regions where the measured external disturbance is more than a threshold.

### Claim 3 (depends on 1)

The disk recording method according to claim 1, wherein the designating of the disk regions comprises designating non-recordable disk region addresses according to an amount of the measured external disturbance, and designating the recordable disk regions according to the non-recordable disk regions.

### Claim 4

A disk recording method, comprising:
partitioning a disk into a plurality of disk regions, and measuring for an external disturbance at each of the disk regions;
setting a disk speed based on the measured external disturbance, and designating disk regions, excluding the disk regions where the external disturbance is measured, as recordable disk regions; and
calculating a maximum disk recording capacity based on the designated recordable disk regions,
wherein the calculating of the maximum disk recording capacity comprises calculating the maximum disk recording capacity based on a recordable disk region address corresponding to an outmost circumference of the disk.

### Claim 5 (depends on 4)

The disk recording method according to claim 4, wherein the maximum disk recording capacity is displayed at a host.
