Faster CD-ROM access is promised by PLI's upcoming 15X CD-ROM drive, based on a PLI-designed mechanism rather than the typical OEM product. The SCSI device, which works in Macintosh, DOS, and Sun environments, provides data transfer of up to 2.25 MB per second and an effective access time of 40 milliseconds (ms), much faster than the 300K per second transfer rate and 300 ms access time offered by drives such as Apple's double-speed CD300. The drive should be available within a month or so, and the list price will be around $1,300. [Pythaeus]
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
