As found on Wörter Rennen mit System
There are 4 sector in regular format on the disk: 18 / 0 18 / 1 18 / 8 18 / 11
The rest of the tracks were written in speed 0. Each of these track contains a single additional regular sector header that was written with speed 3.
The first file is linked to sector 18 / 8 that loads auto start code to the C64 from $02d1 to $03cb. Execution entry point is at $0334.

The floppy has loaded automatically previously t18 s0 to the buffer at $0700. Aside from the disk title the sector also contains code at $0700 and $07b0.
