Abstract

Bloom, which is an increase (positive bloom) or decrease (negative bloom) of the size of a written mark, is a nonlinear effect prevalent in optical recording systems. Two kinds of bloom are possible. The first kind is data dependent, and can be (at least partially) compensated for during writing. The second kind of bloom is caused by over- or under-etching during mastering, thermal sensitivity of the media, or by laser power variations. This can be negative or positive, and cannot be avoided while writing.
