Long delays in optical device mount times are avoided by using a method of reserving space on optical media before it is mounted. This permits users writing objects on the media to continue before the media is mounted and the data are actually written. To reserve space, the method maintains a file on a direct access storage device (DASD) which keeps track of the available space for each optical disk and compares the size of each object to be written to the optical disk to the amount of space available.
