MyISAM Static Vs MyISAM Dynamic

Hello,
please explain the Main or Technical difference between MyISAM static,and MyISAM dynamic?

Here are few points on which we can differentiate Two terms.
1.In MyISAM static all the fields have fixed width. The Dynamic MyISAM table would include fields such as TEXT, BLOB, etc. to accommodate the data types with various lengths.
2.MyISAM Static would be easier to restore in case of corruption, since even though you might lose some data, you know exactly where to look for the beginning of the next record.But MyISAM dynamic is not capable of doing this.

Thanks for your reply, please mention if any other points are there.
