Abstract

In a low-cost disk drive, it is desirable to index the recording head with a fine pitch spiral rather than using a more expensive mechanism for actuating the head in a random-access manner. If the pitch of the index spiral is less than the width of the read/write element in the recording head, the recording head can still be used to read substantially concentric tracks recorded on the media.
