It's a practice that the computer storage industry changed as they developed techniques to cramp more data onto disks (floppy and hard and compact and digital video disks alike). Many disk-based data storage systems read/write data at different rates depending on how far the data tracks are away from the center of the disks so as to keep the data density less varied throughout the usable surface of the disks. (See, for example, "zone bit recording.)quote:Originally posted by Bernard:
The cutting process accounts for the difference in speed. If you draw an angle out from the center of the record, the space within the angle will contain the same amount of information regardless whether on the edge of the record or near the center. The information gets packed closer together as you move towards the center. You're welcome.

Another interesting tidbit: CDs read from the center to the outside, the opposite of records.

...and CDs record at a constant linear rate so the rotational speed changes as the read head moves from the center toward the outside of the disk.quote:Originally posted by CHAS:quote:Originally posted by Bernard:quote:Originally posted by Axtremus:It's a practice that the computer storage industry changed as they developed techniques to cramp more data onto disks (floppy and hard and compact and digital video disks alike).
