Abstract: A multiple transducer disk file format and head addres- sing/switching control circuitry permit reading all sector indi- tifier (ID) fields during a single rotation of the media using uniformly staggered sectors. This results in an average access latency of one-half revolution ofthe media an enables the use of maximum or selectively reduced data rates secured by successively storing data in sectors separated by sector fractions which are multiples of the uniform staggering between sectors within a cylinder.

Abstract: A removable cartridge (200) for a disk drive (30) which has a 1.8 inch form factor, has multifunction features which allow for high data storage capacity at a reduced size. The cartridge (200) includes a cartridge screw (206) which engages the cartridge nut (221) defined in the cartridge housing base (204) for allowing the disk (220) in the cartridge (200) to be positioned relative to the cartridge housing base (204) in order to successfully engage the spindle motor nose (56) of a disk drive (30). The cartridge screw (206) additionally prevents the disk (220) from rattling within the cartridge (200) whether the cartridge (200) is removed from the disk drive (30). The cartridge (200) further includes a multiplicity of projections (212, 214), tang (208), and rails (216) which contact the drive (30) to perform the functions of proper reception and registration of the cartridge (200) in the cartridge receiving mechanism (53) of the disk drive (30) and proper operation of the cartridge (200) as the cartridge (200) is manipulated by the disk drive (30).

Abstract: A flexible hub for a disk (2). The disk includes a relatively large center hole into which a flexible planar member (6) is mounted or clamped. The size of the flexible member is slightly larger than the hole, thereby requiring that the flexible member be slightly bowed or flexed in order for it to fit within the hole. The flexible member is preferably attached to the disk at three respective qui-angularly spaced locations (40) around the periphery of the hole. In the center of the flexible member is a collar (7) adapted to receive a protruding spindle neck (28) from a spindle mechanism upon which the disk is mounted. The end of the spindle neck and the inside wall of the collar are tapered at the same angle. Insertion of the spindle neck into the colar thereby forces alignment or centering of the center of the collar with the longitudinal axis (8) of the spindle neck.

Abstract: A compression arm connector (72) for connecting two circuit substrates (54) in a disk drive and a method of producing the same are provided. The compression arm connector (72) replaces the need for two vertical connectors and a base plate header traditionally used in disk drives for connecting two circuit substrates. Connector (72) is composed of curved members (104, 106, 108) provided in slots (74). Another compression arm connector (56) for connecting wires to solder pads on a circuit substrate is also provided. The contacts of this compression arm connector (56) are bent through an angle of more than 90 degrees to form a deflectable member and a solder member. Both connectors (72, 56) are capable of exhibiting large wipe and deflection capabilities. Additionally, both connectors can be used in a low-cost disk drive provided by the invention.

Abstract: The present invention includes a method, apparatus and disk format for implementation of the same to provide fault tolerant detection of ID fields for data sectors in order to eliminate errors caused by mis-alignment and mis-detection of hard sector marks. Logic is provided to initiate a time-out count at the completion of a hard sector count. The time-out count is specified to be a period of time-within which a hard sector mark should be detected. If the time-out count counts down and a hard sector mark is not detected, then a possible error situation arises and the fault tolerant process is initiated to compensate for the lack of detection of a hard sector mark. Thus, at the end of the time-out count, a small burst count is started. This small burst count is of a shorter duration than the original burst count utilized, but is long enough to bring the head assembly to the location in the sector at the beginning of the user data at which time the hard sector count is initiated to count down the user data locations for that hard sector. Thus, the beginning of the user data area will always be determined and errors due to ill-defined user data areas caused by mis-detection of a hard sector mark are avoided.

Abstract: An ultra-small form factor disk drive system (12) of length about 86 mm, width about 54 mm and height about 13.5 mm or less is based on a 4.8 cm (1.89 in) diameter disk (20). The disk drive system is adapted to fit in an enclosure which is adapted to mate with and fit into a double high PCMCIA connector/slot and/or a triple high PCMCIA connector/slot. For the double high PCMCIA connector/slot, the height of the disk drive enclosure does not exceed 10.5 mm. The system may include a flying head and flexure assembly (34) incorporating a high offset and high preload head for improved head height control and increased recording density across the surface of the disk, a spindle motor (110) integral with the base plate (112) of the drive, a mechanical latch (230) for positive head actuator parking, and mechanical shock detection means (310) to prevent data corruption. The disk drive system can withstand 200 g shocks while operating.
