Data recording write strategy optimisation

A method for recording data on a recording medium, utilising a write strategy model using first, (102, 120), and second parameters, (114), comprising:

• providing the set of second parameters, where the set of second parameters (114), has been obtained by writing a data pattern (106, step 204) by using at least one set of randomised first parameters, (102, step 202), reading the recorded data pattern, (108, step 206), and calculating the set of second parameters (114) based on said read pattern, (110, step 208),
• calculating at least one set of first parameters, (116, step 210), dependent on the set of second parameters, (114), and the data to be recorded, (118), and recording data (122, step 212), in at least one storage location, based the sets of calculated first, (120), and second parameters, (114), and the data to be recorded.

A recording medium, (52, 312, 412), having at least one data block, (314, 414), written in at least one storage location area on said medium, (52, 312, 412), said at least one data block, (314, 414), comprising a data pattern that has been written by using a method utilising a write strategy model comprising first, (102, 120), and second parameters, (114), wherein at least one set of first parameters, (102), is randomised, such that the recorded data pattern, (110), can be read, (108), and the set of second parameters, (114), can be calculated, (112), based on said read pattern, (110).

Write strategy determining device, for recording data, (step 212), on a recording medium, (52, 312, 412), comprising:

• a control unit, (304), arranged to provide at least one set of randomised first parameters, (102),
• a writing unit, (310), connected to the control unit, (304), arranged to write a data pattern, (106), on said recording medium, (52, 312, 412), by using said at least one set of first randomised parameters, (102),
• a reading unit, (316), connected to the control unit, (304), arranged to read said recorded data pattern, (108, 110), from said recording medium, (52, 312, 412), wherein said control unit, (304), further is arranged to calculate, (112), a set of second parameters, (114), based on said read pattern, (110), and based on the at least one set of randomised first parameters, (102).

Recording device, for recording data (step 212), on a recording medium, (52, 312, 412), utilising a write strategy model using first, (120), and second parameters, (114), comprising:

• a control unit, (406), arranged to provide a set of second parameters, (114), where the set of second parameters (114), has been obtained by writing a data pattern (step 204, 106) by using at least one set of randomised first parameters, (102), reading (step 206, 108), the recorded data pattern (110), and calculating (step 208, 112), the set of second parameters, (114), based on said read pattern, (110), and arranged to calculate (step 210, 116), at least one set of first parameters, (120), dependent on the set of calculated second parameters, (114), and the data to be recorded, (118), and
• a writing unit, (410), connected to the control unit, (406), arranged to record data, (step 212, 122), in at least one storage location on said recording medium, (52, 312, 412), based on the sets of calculated first, (120), and second parameters, (114), and the data to be recorded, (118).
