There are more benefits to the large centetr hole on 45s than usually recognised, when used with a single speed 45 changer. Among them are:
1. Simpler change mechanism. No push off or stacking bar mechanism necessary
2. Rapid change cycle
3. All records spin thereby avoiding record skid during change cycle
4. Quieter change cycle
5. Easier to handle records
6. Less center hole wear
7. Inexpensive to manufacture
There are many more advantages when compared with the 78 RPM format it was intended to replace. In that regard, it is a very ingeneous product. The 33 RPM allows an album-length play time, but is too costly for a single play format and fails on many of the other 45 adavntages.
