Storage media having a wide servo band and high data format efficiency and a storage using the same

A servo control method for storage, comprising the steps of:

• providing a head disk assembly including a disk-type storage media having short-format servo sectors recorded thereon including position error signals and full-format servo sectors recorded thereon including track information, and data recorded thereon;
• providing a head which reads the servo sector from the disk-type storage media and which conducts input/output operations of the data to/from the disk-type storage media;
• providing an integrated circuit (IC) for transferring data between the head and the storage media;
• providing a channel for controlling input/output operations to/from the head disk assembly;
• providing a controller for setting a mode of the channel to a servo sector read mode or to a data input/output mode;
• providing a servo controller for demodulating the servo sectors of formats recorded on the storage media;
• and
• controlling the servo controller and the channel with a microprocessor so that only the full-format servo sectors are decoded during a seek operation of the head and only the short-format servo sectors are demodulated during a following operation of the head.
